Little Barrier Island (Hauturu) Supporters' Trust (The Trust) was established in 1997, with the primary objective of supporting and contributing to the conservation of the indigenous values of Little Barrier Island (Te Hauturu-o-Toi) and its significance as a wildlife sanctuary of international importance.

While the Trust has its own specific objectives, it also coordinates its activities with the Department of Conservation (DOC) and liaises closely with DOC officers responsible for the island. Wherever possible, it provides practical support for targeted initiatives that demonstrably benefit Hauturu.

The Trust raises funds to initiate or assist selected projects on the island, particularly where habitat or inhabitants are threatened. It has funded important weed control and eradication programmes, a significant aerial survey, and an urgently needed extension to the tuatara enclosures.

Project funding comes from subscriptions to its newsletter “Hauturu, donations from the Trust's supporters, grants, sponsorships and bequests. The Trust will continue to select projects that will be of direct benefit to Hauturu's endangered animal and plant species. Immediate aims range from further weed control to targeted species protection and research, and educational programmes.

The Trust presents the interests of the island in appropriate forums, in order to facilitate both discussion and the dissemination of information about its status and special needs. In particular, the Trust strongly supports and promotes the need for security of the island and the protection of its flora and fauna from animal and plant pests. Human impact is necessarily kept to a minimum.

Education is seen as a key role by the Trust. Ensuring that the public is aware of the significance of Little Barrier Island/ Te Hauturu-o-Toi and understands why it needs protecting is of paramount importance.

Educational programmes can therefore offer corporate entities a high-profile opportunity to identify with valuable conservation ethics in relation to Little Barrier Island/ Te Hauturu-o-Toi.

The Trust’s current strategy has three integrated elements

  1. Pampas and asparagus eradication. DoC’s goal is to eradicate pampas and asparagus from the island by 2022. That is achievable, but only if LBIST is able to provide substantial financial support.
  2. Research. We wish to support scientific research on the island by offering two scholarships a year to doctorate students.
  3. Protection using technology. The innovative use of leading-edge technologies has the potential to transform the way endangered species are protected on the island (for example, electronic monitoring of nests and traps; use of drones to identify weed patches).



Since it was founded 1997, the Little Barrier Island (Hauturu) Supporters' Trust has played a significant part in the preservation of Hauturu as an internationally important Nature Reserve.

The island is one of the last remnants of "primeval New Zealand". Established as a wildlife sanctuary in 1895, it is viewed by the Department of Conservation (DOC) as "an invaluable refuge for rare and endangered plants, birds and animals whose mainland habitats have been destroyed".

The Trust's primary objective is to contribute to the preservation of the indigenous values of the island and the realisation of its full potential as a wildlife sanctuary.

The Trust raises funds to assist selected projects on the island. It is also helping to educate the public on conservation issues pertinent to the island.


On Hauturu, since the early 1990’s, DOC has run an intensive captive management programme for Little Barrier tuatara, so as to provide for their future release into the natural environment.

This project led to such successful breeding that more living space was needed.

  • In 2002, thanks to an ASB Community Trust grant, supporters' funds, and the efforts of several working parties, the Trust provided a new tuatara enclosure.
  • The Trust actively supported DOC in obtaining its resource consent to eradicate kiore, and played a large part in enabling the appeal against the original proposal to be settled.
  • The eradication programme was carried out in 2004. The subsequent two-year monitoring period and final island-wide survey confirmed its success.

Once rats (kiore) had, like the wild cats before them, been eliminated, Hauturu tuatara could be set free.

The ceremonial release took place on the 12th Nov, 2006.

The next day, 30 tuatara were transferred to remote release sites. More have followed, and are seen to be doing well in the wild, but a core captive breeding population is being maintained in support. The Trust continues to assist with maintenance work around the enclosures and provides funds to help with the cost of materials and food supplies for the tuatara.

Battling Plant Pests

A key target of the Trust's work is weed eradication. Weeds are a major threat to the native plant life and natural environment of Hauturu. In 1996, DOC began a long-term project to tackle the problem, but with limited resources.

When Biodiversity Funds became available, DOC embarked on a more extensive weed eradication campaign.

Selective use of herbicides is needed to eradicate many of these invasive weeds.

  • On the Trust's behalf, Monsanto, Dupont and, more recently, Nufarm have provided necessary herbicides.

The Trust resolved to extend and advance this urgent work.

Climbing Asparagus ( Asparagus scandens ) is Hauturu's most threatening invasive weed; it can both smother and strangle native forest. Every year, the south-western sector of the island is systematically searched, on foot and by abseiling. Every plant found is destroyed.

The Trust is pleased to have hastened progress:

Recent history of our involvement: In 2005 climbing asparagus seedlings were found in the lower reaches of the Orau Gorge.

  • In 2008, the Hauturu Supporters Trust funded a three-day abseil trip into the gorge during which a large number of adult climbing asparagus plants were found. As a result Orau Gorge has been assimilated into the Hauturu weeding project and is grid searched on foot and by climbers on the cliffs annually.
  • An early Tindall Foundation grant enabled the Trust to advance abseiling work on Hauturu's steep cliffs.
  • A number of substantial subsequent grants from ASB Community Trust has enabled this work to continue on an annual basis.
  • More recently, the Chisholm Whitney Family Charitable Trust has made significant grants to the Trust to enable it to contribute financially to this vital work.
  • Donations from Hauturu supporters extended 'on the ground' work over two seasons so that the perimeter of the climbing asparagus infestation was reached and new plot boundaries established.
  • The Trust also provided for the installation of permanent markers for the relevant weed plots.

Pampas ( Cortaderia selloana and C. jubata ) Pampas is an early coloniser of open coastal areas and disturbed sites such as slips. It has the ability to reach distant open spaces quickly and to blanket them with very rapid growth outcompeting and smothering other vegetation. This is of particular concern on Little Barrier as many of the island’s threatened plant species occupy the open coastal habitats. Pampas was first recorded on Hauturu in 1974 and was widespread by 1978. In 2004 a programme was initiated to control these two species. Various methods of control have been used including boom spraying, “wrecking ball” spraying, and personnel strop spraying (often referred to informally as “dope on a rope”). The initial phase of intensive work has been successful and has now been scaled back mostly to follow-up control. Unfortunately, total eradication is not considered feasible because wind dispersed seeds are likely to reach the island from either the mainland or Aotea/Great Barrier Island. Follow-up work will continue to be required indefinitely.

  • A number of substantial grants from ASB Community Trust have
  • The Lion Foundation has also provided significant grants to the Trust to assist with this high priority work.

Mexican devil ( Ageratina adenophora ) and mistflower ( A. riparia ) These species are widely spread.

Prickly hakea ( Hakea sericea ) This had become well established on the south-eastern corner of the island, at East Cape.

  • In 2001, the Trust embarked on a three- to five-year programme to eradicate prickly hakea. Generous grants from the NZ National Parks and Conservation Foundation have ensured excellent progress.

Coastal Weeds

All of the above plant pests, and many more, pose a threat to both on- and off-shore native forests. Seeds and plant material can all too easily be transferred from the mainland by birds, humans, wind, or even sea.

On Hauturu, constant vigilance is maintained against re-infestation and the arrival of new threats.

  • The Trust has publicized the threat posed by coastal weeds, generating a good response from members of the public, concerning both private and public land. Advocacy is ongoing.
  • Hauturu Supporters take part in 'hands-on' work at Tawharanui, the Regional Park nearest to Hauturu, and on Working Weekend visits to the island itself.

Aerial Surveys

  • The Trust has funded two aerial photographic surveys of the island.

The second, after the deluge of March 1998, revealed the massive erosion caused. The survey contributed to operational planning and continues to provide a benchmark for a wide range of scientific studies.

Unique Ecosystem

The Trust will continue with weed eradication work, as it is vital to the preservation of the island's unique ecosystem.

The Trust's first Patron, artist and ornithologist Don Binney, described Hauturu as “arguably the last virtually intact example of northern New Zealand biosphere… It is one of the relatively few island spaces anywhere that has resisted almost entirely human encroachment, social encroachment, and developmental encroachment."

Relationships with DOC and iwi

The Trust works closely with the Department of Conservation (DOC), which manages Hauturu on behalf of the Crown, to support its work in the ongoing protection and restoration of the island’s diverse ecosystems. While the Trust is recognised as a key partner and stakeholder it does not have a formal role in the island's governance structure, which since 2012 has existed as a co-governance relationship between the Crown and the local iwi, Ngāti Manuhiri. The Ngāti Manuhiri Claims Settlement Act 2012 made provision for redress to Ngāti Manuhiri for Hauturu and established this co-governance relationship.

Hauturu is a place of great importance for Ngāti Manuhiri and the other iwi who share ancestral ties to it. Until 1896, the island was a permanent home for Ngāti Manuhiri, a refuge and a burial place for Ngāti Manuhiri rangatira. Gardens on the island and the surrounding sea provided resources for and sustained many generations of Ngāti Manuhiri. Significant cultural remains include stone structures, terraces, middens, burial sites and seven pā. In the 2012 Settlement, the Crown acknowledged the long association of Ngāti Manuhiri with Hauturu and vested the Island to the iwi, who then gifted it back to the people of New Zealand for its continuance as a nature reserve.

As the recognised kaitiaki of Hauturu, Ngāti Manuhiri are actively engaged with DOC in the management of the island. A joint working party between DOC, the Auckland Conservation Board and Ngāti Manuhiri has been formed to support the co-governance arrangement and to develop the Conservation Management Plan for Hauturu. This plan is being developed according to a statutory planning process under the Conservation Act and will take two years to complete.
