It’s Saturday morning in the butterfly garden at Te Puna Quarry Park, near Tauranga, and while monarchs flit and flutter 83-year-old Mary Parkinson is clambering up a rock face to plant a prickly euphorbia, while 80-year-old Norm Twigge tames a wayward shrub with loppers.

The pair, who met as trustees of the Monarch Butterfly NZ Trust, have for the past 2 years combined their talents in the garden, one of the many themed areas in the 32ha park, after Norm, a lifelong butterfly enthusiast, moved to Tauranga from Whakatane.

Mary, NZ Gardener’s Bay of Plenty Gardener of the Year in 2010 and long-time Tauranga Orchid Society member, started helping at the former gravel quarry at the behest of her sister and foundation volunteer, Jo Dawkins, after a large donation of Cymbidium orchids arrived.

The butterfly garden, on a terrace in the area planted with orchids, was developed in 2007 after Mary spotted a self-seeded swan plant amid 3m-high gorse. “Actually, the butterflies invited themselves,” she says. “They found the plant and laid their eggs, all I did was try and give them a home.”

Each year she raises as many monarchs as possible which, at various times, means wasp and preying mantis patrols, as well as hauling buckets of water in summer to keep nectar-rich flowers in peak condition.

“I just keep suggesting things and then have to get stuck in and get the work done,” Mary says, recalling that her offer to stage a Monarch Butterfly NZ Trust conference in Tauranga in 2009 also meant clearing and planting more of the terrace in readiness for a conference visit.

A small hatching house was added when she and fellow volunteer Shona Purves decided to feed caterpillars inside to protect them from wasps. Thanks in part to public response – containers of caterpillars left on site – it was quickly apparent a larger house was needed.

In 2016 Mary and Norm extended the larger, second house in support of a MBNZ Trust project that saw UK conservationist Steve Wheatley and local entomologist Peter Maddison investigate the forest ringlet butterfly, in decline in lowland areas. Norm, who has been recording forest ringlet sightings in the Mt Ruapehu area for 20 years, was also be involved, particularly during the trial breeding phase.

Norm raises admiral butterflies, both red and yellow, in the quarry garden. Loss of habitat is the major problem facing these butterflies as nettles are essential to their life cycle. “This is a public garden so we can’t grow big areas of nettles,” Norm says. “Someone’s always got to touch – even if there are warning signs – which means the size of our admiral populations will always be limited.”

He’s also keen to see if any “migrants” that blow over from Australia – blue moon, painted lady and the lesser wanderer –  can be encouraged to breed.

“The biggest thing is the lack of somewhere warm for them to overwinter,” he says, adding that while living in Whakatane he tried heating a room overnight to see if he could create the right conditions for some lepidopteran visitors. “The power bill soon made me see sense.”

Most butterflies feed on the same flowers and Mary recommends grevilleas, Montanoa (tree daisy), echiums, zinnias, wallflowers and collarette dahlias. “Any cottage garden flowers are good.”

Norm notes many lawn “weeds” are also great butterfly food, including clover and dandelion flowers. “And buddleias are fantastic,” he says. “There are several that don’t seed but sadly they’re all regarded as pest plants. It’s known that butterflies can detect food from 2km away so planting the right things means butterflies in the area will come.”

The white-flowered swan plant and the two brightly coloured Asclepias curassavica (tropical milkweed) provide nectar for monarchs, while the plants themselves play host to monarch eggs, feed the caterpillars and are often home to the resulting chrysalis. Providing enough swan plant for very hungry caterpillars stresses many people, Mary says, and over the years she’s taken in thousands of caterpillars to raise.

In 2016 Mary tagged and released 400 monarchs from March 1 until the end of June “when I ran out of tags”. It’s hoped that anyone who finds or photographs a tagged butterfly will go to the MBNZ Trust website and record the “white dot” number and where the insect was found so giving researchers an idea of how far the insects travel and clues to where they cluster to overwinter.

The park’s lone swan plant of 9 years ago has morphed into many more, both in the butterfly garden and beyond, although Mary accepts they need thinning to stop them spreading too far.

“If you’re worried about swan plants seeding through your garden, snip off the green pods before they burst,” she advises. “Swan plants don’t have a long life, maybe 3 or 4 years, so you want at least one new one coming on each year.”

Feeding notes:

See a list of nectar plants to feed butterflies at the MBNZ Trust website.

When buying swan plants from garden centres check they are spray free and keep your garden spray free.

Keep some swan plants under wraps (old net curtains, mosquito nets) so not all have eggs on them and/or are eaten.

Pumpkin can be used as food only at the end stage of a caterpillar’s life (2cm+). Any earlier and the butterfly will emerge deformed.

Wasps, ants, preying mantis and passion-vine hoppers all predate on one stage or another of the butterfly life cycle.

Lend a Hand: Mary and Norm are always looking for helpers. To volunteer simply turn up at Te Puna Quarry Park at 9am on a Tuesday, taking your own smoko.

Farewell Heather Young

It’s with great sadness that I farewell one of the Western Bay’s champion gardeners – and a great friend.

Heather Young, who for the past few years had been living in suburban Katikati, got to grips with gardening after husband Francis took up a post at the University of Illinois in Champaign-Urbana in the late 1960s. During the Kiwi couple’s stay, Heather gained a bachelor’s degree in ornamental horticulture and a master’s in extension education. After teaching in the university’s plant biology department for 7 years, Heather began teaching ‘master gardeners’ botany and composting.

Although there was only a very short growing season in Illinois, Heather remembered the “jungle-like” growth when it did happen.

When Francis retired in 2000, the couple moved to their harbourside property south of Katikati and began developing the boggy paddock into a garden that, when they sold it, featured five ponds and several dry stream beds (wet in winter), all feeding into the main drain beside the harbour.

“We raised some beds with truck loads of horse manure but anywhere there was a wet patch we made a pond,” Heather told me in 2008. “It’s no use fighting it.”

The couple ran the garden on sustainable lines but Heather noted that plenty around the garden – which featured many artworks and a palisade-type fence around an extensive vege garden – was there purely for pleasure. They enjoyed planting unusual trees and shrubs, particularly those from the US.

Heather and Francis opened Matangirau for several Tauranga Garden and Artfests, and Heather was also instrumental, while president of the Katikati Herb Society, in opening the (now-gone, sadly) society’s potager at Aongatete, designed to be a teaching place for those interested in herbs.

Francis and Heather both volunteered at Te Puna Quarry Park for a number of years before stepping away to pursue other interests.

This is only a once-over-lightly of a busy life that included preserving, amateur theatre and generally having fun. Heather was unflappable, always smiling, a wealth of knowledge and will be much missed. Kia kaha Francis and family.

Happy Birthday Quarry Park!

Volunteers old and new gathered for lunch today at Te Puna Quarry Park to mark 20 years since the first work day – with people who were at that first event recalling how daunting the task seemed with blackberry, gorse, pampas grass and wilding pines everywhere (not to mention the goats, rabbits and possums)!

But start they did, and now – 20 years later – the park is “the jewel in the Western Bay crown”, according to Cr Don Thwaites who was standing in for Mayor Garry Webber, and all built on volunteer labour.

The Vege Grower was the park society’s foundation treasurer and I occasionally help out with publicity so we’ve known the place since its inception. Today, the Vege Grower recalled hearing blasting from his childhood home when the site was still a working quarry and he was also able to clarify why there aren’t many photos from the first work days – there was nowhere to get a shot from, the place was a jungle!

Shirley Sparks, who got neighbours interested in redeveloping the site as a public park and is now the society’s patron, recalled how she and husband David would often be milking when blasting took place. “You can imagine the animals’ reaction to the noise. Unfortunately for us we were standing below the cows’ tails …”

Society president Ian Cross paid tribute to “the three ladies of the quarry” – Shirley, Jo Dawkins (who seems to spend every waking moment working at the quarry, bar Wednesdays (golf day) and who is a plantswoman par excellence) and Dulcie Artus, longtime secretary, former longtime treasurer, until recently longtime QuarryFest organiser, website worker, brochure designer … what he didn’t mention was writer of funding applications which I know from experience is a tedious, and often thankless, task.

I apologise for the quality of the photos, taken on my phone (won’t do that again).

Amid much banter two kauri trees were planted by Tauranga Mayor Greg Brownless (left) and Western Bay of Plenty District councillor (and quarry neighbour) Don Thwaites. Photo: Sandra Simpson

The two council representatives called on 99-year-old Alf Rendall, who is still a regular volunteer, to lend a hand with the second tree. (Photo-bombing the shot at bottom left is Bay of Plenty Times photographer George Novak.) Photo: Sandra Simpson

The formalities concluded with a release of monarch butterflies. Pictured from left are Greg Brownless, Don Thwaites, Jo Dawkins, Mary Parkinson (founder of the butterfly garden, orchid garden and sister to Jo) and George Novak. Photo: Sandra Simpson

Fluttering by

UK conservationist Steve Wheatley has landed at Te Puna Quarry Park to work with Katikati entomologist Peter Maddison and Tauranga butterfly expert Norm Twigge on an investigation of the rare native forest ringlet butterfly.

The Monarch Butterfly NZ Trust has brought out Steve, who works for the Butterfly Conservation Trust and is on a 3-month sabbatical, especially for the project. He will be based in the Tauranga area until Christmas, then moves on to Auckland and the South Island.

Norm has been recording forest ringlet sightings in the Mt Ruapehu area for 20 years and says there are six or seven areas nationwide where the butterfly is found but not a lot is known about breeding patterns or why Dodonidia helmsii is declining in numbers in lowland areas, so it’s hoped this project will fill in some of those gaps. According to the Nature Watch website, the butterfly has become “significantly rarer over the last 50 years”.

The park’s butterfly garden features in the December issue of NZ Gardener and includes interviews with the garden’s founder Mary Parkinson and, since he moved to Tauranga from Whakatane a year ago, her right-hand man Norm.

Flowering now

Not in my garden, alas, but Te Puna Quarry Park yesterday. I hope you like the photo gallery (which seemed to sort itself into colours).

And now for the pinks …

The only redeeming features of the seedy and weedy Prunus campanulata (Taiwanese cherry) – many would say – are its colour and being a food source for birds, like this one-eyed tui. Photo: Sandra Simpson

Te Puna Quarry Park is off State Highway 2, about 15 minutes north of central Tauranga. It’s open seven days from early to dusk and admission is free, although donations for the volunteer project are always welcome (donation bin is by the main entry gate) – as are helping hands. If you’d like to meet new people and are reasonably active (age no barrier), volunteers work on Tuesdays from 9am (take morning tea) on various tasks, but weeders are always welcome, and quit at noon. To find out more  phone Ian Cross, 07 578 8735, or email society secretary Dulcie Artus.

Weeds, pests & a new hero

I spent last weekend in beautiful Wanaka at the Aspiring Conversations festival. I was very excited to hear Tim Flannery (scientist and founder of Australia’s independent Climate Council), climate researcher Suzi Kerr and science communicator Veronika Meduna talk about climate change.

Relevant to gardeners and farmers was that in New Zealand we can expect more dry days in winter and spring although the rain that does fall will do so in heavier and more intense bursts which will mean more flooding.

More insect pests will make it through milder winters, meaning populations will not make a slow gain as spring continues but already be strong and in good numbers at the start of spring. As someone who doesn’t spray, this was worrying. Personal experience tells me that a cold snap in winter really knocks back pests that would otherwise over-winter in good numbers. Balance will be lost.

Another comment was that the planet doesn’t need us to save it – in fact, it doesn’t need us at all!


The fruit of Cornus capitata are, apparently, edible, although can be bitter. The birds were certainly leaving them alone. Photo: Sandra Simpson

I stayed in the Wanaka Hotel, which featured a Pye radio fitted to the wall above the bed (I didn’t try it). Saw an interesting tree from my balcony so nipped down to photograph it and on the morning I was leaving was lucky enough to meet the knowledgeable owner(?) who this weekend is at the Dendrology NZ conference at Eastwoodhill Arboretum.

Cornus capitata, he said, strawberry tree. Although native to the Himalayas, India and China, the Waiere Nursery says it tolerates only light frosts, while the Weedbusters website lists it as a pest, although doesn’t stipulate whether that is New Zealand wide.

The fruit, which is what I spotted, forms at the centre of a ‘flower’ that is in reality four pale petal-shaped bracts. The Missouri Botanical Garden website notes that it is not reliably evergreen and in colder areas may drop foliage.

A weed that’s been making the news – and sounds rather alarming – is velvetleaf. It has been found in fooder beet crops in both the North and South Islands and the Ministry of Primary Industries (MPI) is asking for help.

Search and destroy activities have been conducted on more than 600 properties since March when velvetleaf was discovered in several regions with the weed found on 215 properties in 11 regions to date.

Dr Veronica Herrera, director of investigations, diagnostics and response, says MPI is continuing to investigate how contaminated fodder beet seed entered New Zealand and has beefed up border inspections.

“MPI has already established that some lines of fodder beet seed grown in Italy and pelletised in Denmark were contaminated with velvetleaf. These lines have been banned from entry into New Zealand.” MPI’s velvetleaf hotline is 0800 80 99 66.

I know some people don’t take our biosecurity very seriously – and it can be jolly annoying not to be able to buy bulbs in Schiphol Airport or to leave flower seed or a cutting in a foreign garden – but this is why we should. Farming, forestry, horticulture and floriculture are how some families earn their living so every incursion is a threat to someone being able to put bread on the table for their kids or a roof over their heads.

Meanwhile, Honshu white admiral butterflies (Limenitis glorifica) have been released to combat the pest plant Japanese honeysuckle (Lonicera japonica). “The big issue with Japanese honeysuckle is that because it’s a climber it’s really hard to kill with herbicides without killing the thing it’s climbing on at the same time. Biocontrol is seen as a friendlier way to control it,” says Landcare Research scientist Quentin Paynter.

And with nothing to predate on it – until now – the plant has became a major problem in some areas.

The white admiral butterfly was chosen after field surveys in Japan indicated that it is found in a variety of habitats from hot lowland sites to cool mountain areas, suggesting it should be able to adapt to New Zealand.

The release of the first butterflies in 2013 in Wellington and the next year in Waikato was a milestone after numerous setbacks including disruption to the research programme because of the Canterbury earthquakes and the 2011 tsunami in Japan.

Japanese honeysuckle was introduced to New Zealand as a garden plant but has become firmly established in bush environments – and grows up to 15m a year in ideal conditions. White admiral caterpillars feed exclusively on Japanese honeysuckle.

The latest newsletter from Te Puna Quarry Park reveals that they’re trying to establish a white admiral colony there. It appears they’ve succeeded in establishing a yellow admiral population, but no luck yet with the red admirals.

Ringmaster Barry back in action

Barry Curtis could be called the voice of the Tauranga Orchid Show, thanks to the popular repotting demonstrations he has been running for several years – and he will be back again at this year’s show from Friday to Sunday at Tauranga Racecourse.

“I saw it as something I could do,” says Barry, who has been president of the Tauranga Orchid Society for about 10 years. “Having been a school principal, I am confident speaking to groups.”

After retiring from teaching in Auckland, Barry and wife Elizabeth moved to Tauranga to run a motel and also grew callas commercially in Pyes Pa. The couple shifted to just south of Katikati about 11 years ago.

“My Dad grew a few cymbidiums in his tomato house and, when he was no longer able to care for them, I took them on,” Barry says. “I’ve always liked taking a plant and seeing what will come out of it – it doesn’t have to be the biggest or the best to interest me.”

Most hobby orchid growers start with cymbidiums and move on to more exotic plants but Barry has hundreds of the easy-to-grow beauties in his collection.

“The great thing about cymbidiums is that you don’t need an orchid house – they’re happy in the garden, particularly under trees. I keep mine in pots and growing bags so when they flower I can move them to the front door and enjoy them for months.”

Barry, who is also a volunteer in the orchid garden at Te Puna Quarry Park, says that when it comes to growing orchids outside the only no-no is full (burning) sun. Filtered light is perfect.

“Pot them in bark, not soil, and put them in a pot that is only just big enough for the roots, otherwise it takes too long for the plant to feel happy. Orchids need repotting when the bark starts to break down because the soil-like crumbs suffocate the roots – in the wild, the vast majority of orchids don’t grow in soil so need air round their roots.”

In his talks, Barry also shares easy-to-understand information on how a cymbidium grows, including what the pseudo-bulbs do (food storage) and how to split a mature plant.

He says people often worry about which fertiliser to use but “you can use any house plant fertiliser if it is mixed below half the strength it says on the container”. Otherwise, his recommendation is to throw on a handful of slow-release fertiliser twice a year. Barry makes up a special slow-release mix for orchids that is available at the show for a reasonable price.

Garden art from the Junktion

John Hilhorst is always on the lookout for “interesting stuff” and has sheds full of odds and ends – fortunately wife Karen shares his passion for creative recycling.

The couple are behind one of Te Puna Quarry Park’s newer sculptures, Great Balls of Wire, a set of three balls made from barbed wire and mounted on a central post.

“You can’t use barbed wire on boundary fences on public roads anymore,” John says, “so there has been some old stuff around. We’ve sourced some from Karen’s brother’s farm in Waikato but we’ve used it all. We advertised for more but didn’t have any replies.”

Karen made her first ball wearing shearing chaps and a leather glove to handle the wire. “But one hand had to be free to use the tool to join the pieces,” she says. “It was pretty hard on my skin.”

That ball sits in their Tidalwood garden south of Katikati, and it was this that John and Gay Ireland saw on a visit.

“We’ve known the Irelands for years – we bought their Mamaku dairy farm 25 years ago and have been friends ever since,” Karen says.

The Irelands commissioned a barbed wire sculpture for Te Puna Quarry Park, where they are both long-time volunteers. Karen refined her original design and John helped her make the three-tier Great Balls of Wire.

A walk round their garden reveals their quirky sense of humour – Faulty Towers is a collection of op shop pottery fixed to clay irrigation pipes, a set of stocks and a knight were made by John for a mediaeval-theme birthday party and the Orbitron is an old railway flour carrier converted into a children’s playhouse by John.

At Karen’s request he made a palisade-style fence around their potager, primarily to keep out pukeko and rabbits. A neighbour was so impressed she ordered one too, but about five times larger.

“ It was quite a job,” Karen says, “especially doing the points. There are four varying lengths and John fixes them in randomly.”

Karen, who used to do mosaic work, goes to pottery classes and makes art from groups of recycled objects, such as candlesticks or colanders, while John is restoring an old truck (he’s made a sign from the deck – General Junktion) and sculpting a recycled block of Oamaru stone.

“We’re always looking for things that may be interesting one day,” he says.

“We bought home a trailer-load when they closed the museum at the Historic Village [in Tauranga] and when we go away anywhere we’re always on the lookout. One thing about this though, you’ve got to have a reasonable-size shed.”

Making a difference

A lifetime – two lifetimes – spent working with plants and flowers has taken a new twist as sisters Mary Parkinson and Jo Dawkins put their energies into helping develop Te Puna Quarry Park,  the Western Bay’s premier public garden.


In 2005 I managed to get these two busy bees to stand still long enough for a photo. They haven’t changed much. Photo: Sandra Simpson

Born on a farm in Oropi, near Tauranga, the sisters grew up surrounded by a large, lovingly tended garden. Their father, Arnold Shanks, had emigrated to New Zealand from Northern Ireland and met their England-born mother, Christine, on a ship when returning to Britain on a visit. She was going home after a stay in South Africa.

And it was their father who was the keen gardener, although they say both their parents loved “beautiful things” and the home and garden were decorated accordingly.

Volunteering at the outbreak of World War 2, Arnold was sent to Greece, captured and spent four years in an Austrian prison camp. “He said the only thing that kept him sane was thinking about the garden and always redesigning it,” Jo says. “He had a small tin of watercolour paints with him and we still have some of the paintings he did of his ideas. The love of gardening kept him going.” The 0.4ha garden comprised a tennis court, lily ponds and flower beds and was the scene of annual church garden parties after the war.

Mary’s first ambition was to become a marine biologist, dropped, she says, because she couldn’t swim well. Instead, she opened a florist shop at No. 2 Devonport Rd in Tauranga in 1956. “The shop became available and opportunity strikes only once, although I was terrified about going into business,” she says. And it may have been an inherited talent from her father – who had created his bride’s elaborate bouquet for their wedding in 1933 – which nudged her in this direction.

Vogue Flowers was a success, although Mary says “we made a lot of friends but not much money”. Highlights included making presentation bouquets for visiting Queen Sirikit of Thailand in 1962 and one of water lilies for Queen Elizabeth for her visit in 1963.

When their mother became ill with cancer and wanted to make a final return to England in 1958, Mary handed the business to Jo, who was part-way through teacher training. After her mother’s death, Mary worked as a florist at London’s Savoy Hotel where she prepared arrangements for such people as Princess Margaret, ballerina Alicia Markova and flamboyant pianist Liberace who always wanted a floral grand piano.

While in London, she attended the Cordon Bleu school run by the doyenne of 1950s English domestic style, Constance Spry. “We cooked in the morning and did flowers in the afternoon,” Mary recalls. “They were big, massed arrangements which complemented the houses they were in.”

On her return, Mary rejoined Vogue Flowers until the birth of her first child in 1963, when she sold the business.

But she and Jo have never stopped working with plants – they both worked for John and Mary Ewart when they began to grow Tauranga’s first commercial carnation crop, while Mary has had a nursery specialising in kiwifruit seedlings, and Jo has a citrus orchard and garden nursery.

“There’s a lot of pleasure to be had in planting a seed and watching it come up and flower,” Mary says of their lifelong interest in growing things.

She is also something of an orchid expert, having joined the Tauranga Orchid Society 30 years ago and also has previously run a business hybridising and exporting South African disa orchids.

But even Mary admits she had no idea the orchid area at Te Puna Quarry Park would become what is believed to be the largest outdoor planting of cymbidium orchids in the Southern Hemisphere.

Jo, whose home is in the shadow of the former quarry north of Tauranga, has been part of the community project since it began almost 20 years ago and has served a term as president of the society’s committee, while Mary joined the volunteer workers 18 years ago.

“It’s great to be part of a volunteer group creating something for the community,” Jo says. The park has always placed an emphasis on art too, and work in the park includes sculpture, mosaic and pottery.

“It’s such a magical place,” she says, “but it was very hard in the beginning, as a gardener, to adjust to the size of it. It was no good planting just one of something, we had to think in big drifts.” More than 4000 cymbidium orchids might be described as a big drift. “We were lucky the orchids were the first plants to arrive and we could choose a site,” Mary says.

Four truckloads of “fill” orchids, donated by former nurseryman John Kenyon, began the planting and since then almost all the plants have been donated. To plant them on the steeper banks, the orchids were rolled down and Mary and her helpers (most in their 70s and 80s) clambered after them and chipped them in where they stopped. The orchid area now features several other varieties as well, so there’s always something flowering.

These days Mary’s most often to be found in the butterfly garden, a project that had its genesis in 2006 when she saw a swan plant growing in a patch of weeds on the “middle terrace”.

A grant from the Bay of Plenty regional council’s Environmental Enhancement Fund paid for a butterfly hatching house (and to protect caterpillars when predators are about) and a noticeboard, while in 2009 Wildflower World began a relationship with the garden donating seed to extend the butterfly area for a Monarch Butterfly New Zealand Trust conference in Tauranga which Mary, then a trustee, organised.

During the breeding season Mary often responds to calls to rescue monarch caterpillars that have run out of food and has been trying try to establish a population of native red admiral and yellow admiral butterflies at the quarry. She’s at the quarry most days when the butterflies are hatching, and on hand for regular school visits. “When the ‘wild kids’ are given butterflies to hold it transforms them – the big smiles make it all worthwhile,” she says.

Jo, a former president of the International Plant Propagators Association, and Mary have developed a sub-tropical area, bounded on one side by Australian natives, including a prostate Banksia and winter-flowering grevilleas, much loved by birds, and on another by South African natives.

And they have both, along with grandchildren, created a mosaic “pool” at the bottom of a tumble of rocks which suggested itself to Jo as a dry waterfall. Small wooden “bridges” on the path add to the illusion.

Among plants of interest in this area are Chorisias (monkey no-climb trees) with trunks full of thorns and requiring some lateral thinking when it came to moving them for planting, a red banana palm and a rare pink version (in New Zealand) of the Tibouchina shrub.

Jo has planted about five varieties of the Araucaria family, which includes monkey-puzzle and Norfolk Island pines, near the Chorisias, and groups of maples and magnolias in a new area, as well as a tackling a steep, hot bank which is being filled with grevilleas, native to Australia.

“We are especially grateful for the generosity of commercial and private growers,” Jo says. “We don’t have the finances to rush out and buy, for example, 50 hibiscus plants, but if we ask for, say, three we usually get 12.

“The quarry park isn’t a botanical garden, but we do want it to be botanically interesting,” she says. “The rewards for our hard work are to see people enjoying it.”

Te Puna Quarry Park is signposted off State Highway 2, just north of Te Puna, and is open daily during daylight hours. Free admission but a donation is appreciated.
