Their Story
Pirita — leafy native mistletoes — once filled New Zealand’s beech forest canopies with bright blooms. These parasitic plants live attached to large host trees and rely on nectar-feeding birds like korimako and tūī for pollination and seed dispersal. However, they have declined dramatically throughout Aotearoa. The Sanctuary offers refuge to surviving populations of mistletoes, giving visitors the chance to spot these rare forest gems.
Mistletoes are recognised by their pendulous clusters of leaves hanging high among the canopy of their host trees. The green and white mistletoes have small, generalised flowers, and are hosted by a wide range of trees. The red, yellow and scarlet mistletoes have large and bright flowers that are highly specialised for bird pollination. These three species are generally only found on beech trees. brooksanctuary.org.nz
The beech mistletoes can grow high in the canopy, often unnoticed unless in flower. Their flowers remain closed unless opened and pollinated by certain endemic birds and bees. Mistletoes are also exclusively dispersed by birds as their sticky seeds need to be excreted onto a suitable host branch. brooksanctuary.org.nz+1
The beech mistletoes flower around Christmas; and fruit throughout Autumn, sometimes all the way up into Spring. When the seed germinate, a root emerges and plunges into its host, plunging into the xylem tissue that is responsible for carrying water from the roots to the leaves. The mistletoe uses its leaves to create sugars in order to grow. Mistletoes are generally as long lived as their hosts, some probably reaching one hundred years old. brooksanctuary.org.nz
The distribution of mistletoes was linked to the distribution of their hosts, with the beech mistletoes most common in the South island where the most extensive beech forests occurred. The other two species were broadly distributed in broadleaf and coastal habitats where a wide range of hosts grew. One species was endemic to the North Island and has now become extinct. Mistletoes are currently distributed in places where they could survive, often in high altitude forests. At the Sanctuary, green mistletoes are relatively common in lowland forest. Yellow, red and scarlet mistletoes are recovering in small pockets. Tāpia, white mistletoe, has been reintroduced into the Sanctuary in the regenerating bush.
Pirita is under threat from browsing by introduced mammals—particularly the brushtail possum—and from the widespread loss of their pollinators. All species except for green mistletoe are considered at risk of extinction, with one species already gone.
Brook Waimārama is uniquely positioned to protect these species, being primarily beech forest and populated with huge numbers of korimako and tūī which both pollinate and disperse mistletoes. The sheer size of the Sanctuary allows for restoration of native flora at a massive scale, protecting plant communities at a wide range of altitudes, where different species of beech and mistletoes occur. Here, mistletoes will slowly become as conspicuous as they once were.
🪶 The māori name pirita is shared among all the Loranthaceous mistletoes as well as the supplejack vine(Ripogonium scandens). The word is derived from ‘pilita’, the polynesian word for yams. There are around seven other māori names referring to mistletoes and their flowers.

🪶 Ngahere Neighbourhood: piriwai (spiny gilled mayfly)
Tiny, ancient, and found only in Aotearoa — the spiny gilled mayfly (Coloburiscus humeralis) spends up to four years underwater before living just a few days as an adult.
Piriwai can only survive in clean, fast-flowing streams. Its larvae cling to river rocks, filtering food from the water with tiny hair-like gills. They are an important sign of healthy freshwater ecosystems, so much so that this species gets a rating of 8-9 on the sensitivity/stream health rating. All native stream macroinvertebrates are ranked in terms of their sensitivity and used as a bioindicator of stream health.
The Sanctuary stream is a reference site for stream health and represents a `pure`, unadulterated site and thus is highly diverse in sensitive stream invertebrates.

Their Raucous Call Returns: Kākā Set to Reclaim the Brook Waimārama Sanctuary. 🦜
This March, we’re scheduled to welcome two male and one female kākā fledglings from the Dunedin Botanic Garden kākā breeding programme. There’s also the potential for a further four birds to arrive in May.
Kākā are unique to Aotearoa and are nationally vulnerable, with populations heavily impacted by introduced predators. Releasing them into a pest-free sanctuary with ideal habitat (old growth beech forest) gives them the best chance to thrive.
This release will build on years of species translocations as part of the Sanctuary’s ambitious ecosystem restoration efforts, including:
🏠 Kākāriki karaka in 2021
🏠 Powelliphanta hochstetteri consobrina (giant snails) in 2021
🏠 Tuatara in November 2024 and May 2025
🏠 Kiwi in May 2025
Over the coming weeks, our team will be busy planning and preparing for this important translocation. We’ll share more details on timing and what to expect closer to the date.
Thank you to our community of donors, volunteers, business supporters, and Sanctuary Members for continuing to back the Sanctuary — your support is vital to every species return. We can’t wait to celebrate this next milestone with you.

Looking for a unique and memorable date night? 🌙🌲
This February, we’re introducing Date Me Darling — private, curated date nights inside the Sanctuary at dusk.
Three styled locations. One couple at a time. You’ll have a styled spot along the main loop track, locally sourced food and drinks, a few games to share, and time to slow down together as the forest shifts into evening.
Beech Glade: for when you want the world to fall away — deeply hidden, totally private, just you and the hush of the forest.
River: crystal clear water, canopy above, flickering lights — the kind of setup you usually only see on Instagram.
Meadow: open sky, long grass, and the forest standing quietly at the edges like it knows not to interrupt.
Bookings are open now (limited spaces in February only so don’t miss out!): Link in bio

Two cute to be true?
Brook Waimārama Sanctuary and @savethekiwinz teams have been busy over the past few days tracking and recapturing kiwi to remove their transmitters. Thanks to a huge team effort, all ten males were recaptured within just three days.
Some nest burrows held a surprise or two — in several cases a female was present, and a couple even contained chicks. One burrow amazed us all, with not one but two adorable chicks 😍
All chicks are fully independent at this stage of the season, and after quick health checks and transmitter removal, all adult kiwi were safely returned to their burrows.
This special footage was captured by kiwi handler Tamsin from Save the Kiwi, who led the transmitter removal mahi.
We estimate the 20 females and 21 males released in May last year have already produced around 10–15 kiwi pukupuku (little spotted kiwi) chicks in their very first breeding season — a strong sign the habitat is just right.
With transmitters now removed from all ten males, the kiwi are completely free, with no further handling needed. Annual kiwi call counts by staff and volunteers will help track the growing population across our 690 ha, ring-fenced, pest-free sanctuary.
