Predator Free Rakiura is an ambitious and courageous project to help our community and nature to thrive together by removing predators. Drawing on the combined efforts of so many within our community, this map shows Stewart Island / Rakiura’s current predator control, biosecurity work and pest-free sanctuaries.
Help us fill the gaps, as we work to develop a single project which aims to remove the predators and create a natural haven for our taonga, forever. Only together will our vision become a reality.

An incredible amount of work towards a predator-free Rakiura has already been achieved by iwi, the community and various organisations.
Many people on and around Rakiura are doing their bit to control predators and keep their properties, homes, vehicles and vessels rat-free.
Our aim is to provide an environment where native plants and animals are thriving – not just surviving – on and around Bluff Hill. We are dedicated to the restoration and protection of the natural environment on and around Bluff Hill. We do this through pest control, habitat restoration, species translocation and raising public awareness.
Predators: Possums, feral cats, rats, hedgehogs, weasels, ferrets and stoats
Operating since: 2008

The Department of Conservation (DOC) undertakes predator control across multiple areas on and around Rakiura. Below is a summary of their work.
Tiwai peninsula: We aim to control predators of ground-nesting birds, and to minimise browsing impacts on sensitive ecosystems like the coastal turf fields at Tiwai. DOC has a trap network across Tiwai peninsula, Awarua Bay and Waituna lagoon and boardwalk. There are also trap lines along the coast from Tiwai to the start of Fortrose dunes. In addition vessels out of Bluff destined for the sub-Antarctics are checked for rodents and are fitted with bait stations on board for biosecurity.
Predators: Mustelids, rats, hedgehogs, possums, rabbits, blackjack and cats
Rakiura mainland possum control: DOC undertakes cyclical pest control over nearly 32,000ha to enable our forest ecosystems to thrive with healthy a canopy, increased bird and invertebrate survival rates and increased nesting success.
Operating since: 2002
Pest free islands: DOC directly manages 3 pest-free island sanctuaries near the main island of Rakiura through biosecurity surveillance and incursion response. Codfish Island/Whenua Hou is a nature reserve primarily used to manage a breeding programme for the critically endangered kākāpō but is also a sanctuary for a range of other threatened species. Bench Island/Waitaua is a nature reserve sanctuary for invertebrates, coastal plant species and hoiho. Ulva Island/Te Wharawhara is an open access sanctuary for a range of threatened bird and plant species and one of Rakiura’s major tourist attractions.
Predators: Rodents are the main targets of biosecurity surveillance and incursion response as they are the most likely invaders either via swimming from the main island or being transported on vessels. Other pest species are also targeted with surveillance and incursion response to ensure the island sanctuaries remain entirely pest-free.
Operating since: Whenua Hou was gazetted as a Nature Reserve in 1986 and was made pest free in 1998. Ulva Island was first deemed a reserve in 1899, one of the first of its kind in New Zealand and was made pest-free in 1997. Bench Island was gazetted as a reserve for flora and fauna in 1926 and later became a Nature Reserve when the Reserves Act was enacted in 1977. Bench has never had possums or feral cats and rodents were eradicated in 2005
Rakiura mainland Southern New Zealand Dotterel Recovery Programme: DOC’s Southern New Zealand Dotterel Recovery Programme includes a variety of projects with the common aim of saving the critically threatened population from extinction. A major component of the programme is a multi-species predator control project which aims to suppress populations of predator species which kill or destroy dotterel adults, chicks and eggs.
Predators: The primary predator species targeted are feral cats and white-tailed deer. Rodents are controlled to reduce interference with our feral cat control methods. Australasian harriers and spur-wing plovers are additional native predator targets as these are known to eat or kill dotterel chicks and destroy eggs in nests.
Operating since: 1994
Native Island: Native Island is covered with a grid of Good Nature A24 self-resetting traps which aim to reduce the resident rat population to very low levels and quickly reduce the impact of regular incursions from the main island which is only about 60 metres away.
Predators: Norway, ship and kiore rats
Operating since: 2013
Pearl, Anchorage and Noble Islands: DOC maintains possum exclusion on three large islands near Port Pegasus/Pikihatiti including Pearl, Anchorage and Noble Islands.
School kids: Fortnightly checking of four rat traps at Bush school. Weekly checking of approximately 15 rat traps around the school with SIRCET's Pest Manager
Operating since: July 2018

The Mason Bay rat trapping project covers approximately 300ha of coastal forest situated amongst a broader dune ecosystem. Mason Bay represents some of the only intact temperate dune system in the southern hemisphere, stretching inland up to three kilometres and reaching over 200m in height. It is home to a range of locally endemic plants and animals, including many threatened species. The location is a key wintering site for the critically endangered Southern New Zealand Dotterel which rest here during the high tides before flying across to places like the Freshwater River mouth mudflats to feed during the low tides. It is home to one of the largest and most visible populations of Kiwi in New Zealand as well as a range of forest bird species such as red-crowned parakeet, kereru, kaka, tui, bellbird, tomtit, fantail and more.
NZDA members (six teams of three people) maintain and rebait a network of 309 victor rat traps every year Control trips are targeted to spring and summer and generally range from August to December. The primary aim of the project is to increase the productivity of nesting forest birds during their vulnerable breeding season by reducing rat density and therefore rat predation of eggs, chicks and disturbance of incubating adults.
Operating since: Project underway since 2006

Ōmaui Landcare Charitable Trust have a grid system of 573 A24 gas operated rat and stoat killers. They need to be rebaited and gassed twice a year. For possum control we employ a contractor to poison when the RTC shows that it is needed. We have a network of approx 500 bait stations on a grid system for this purpose. Currently we are not controlling cats but, will be putting a plan together probably over the next year.
Predators: Rats, stoats, possums.
Operating since: We commenced operations on a small scale in June of 2013.

Check vessels which regularly travel to Ulva Island, e.g. water taxis, ferry, charter boats, to ensure they are rodent free. Advocate for maintaining a pest free Ulva by connecting with visiting school groups, talking about what needs to be done and why, and checking bags before they depart for Ulva. We're also on call to respond to requests for help locating / removing rodents from any local vessel (many fishing boats work and moor near other rodent free islands around Rakiura).
Predators: Rats and mice
Operating since: 2013

In order to support the ongoing efforts across Southland and to find a way to move us closer towards the predator free goal, a joint initiative of Ngai Tahu, Environment Southland, the Department of Conservation, Gore District Council, Invercargill City Council and Southland District Council has resulted in the formation of a governance group and the joint funding of the role of a Predator Free Southland Coordinator.
The coordinator focuses on establishing a collaborative network including community groups and agencies across Southland, identify the necessary capability and capacity in order to find solutions and funding, determine priority projects to focus our efforts on, and create a framework and 5-year action plan for Southland to collaborate at scale to control our predators and protect our biodiversity.
QEII National Trust is an independent charitable trust that partners with private landowners to protect natural and cultural heritage sites on their land with covenants. A covenant is an agreement between QEII and a landowner to protect land forever. The landowner continues to own and manage the protected land, and the covenant and protection stays on the land, even when the property is sold to a new owner.
QEII partnerships have created a growing network of over 4,600 protected areas throughout Aotearoa, ranging from small backyard patches to huge swathes of high country. These covenants protect more than 187,000 ha of private land, and these play a hugely critical role as a refuge for some of New Zealand’s rarest and most endangered biodiversity and ecosystems.

The Rakiura Hunter Camp Trust was formed in the late 1990s to clean up camp sites, stop bush degradation, help stop conflict with different user groups by keeping hunting parties separated from tramping parties, etc. The trust has built 26 new huts, and extensively upgraded a further two, making a total of 18 huts that they maintain under a concession lease.
Predators: Rats, cats and possums at each hut site.
Operating since: late 1990's
The Neck project up till now has focussed on the removal of possums and more recently deer. However, a successful application to the DOC Community Fund resulting in $156,000 will enable us to add cats and rats to the list of predators. The project started in 2007 and the effects of the possum control during this time has resulted in the flora undergoing a huge improvement. The evidence for this improvement has been gathered using 20 fixed photo point stations around The Neck with a replicated set of photographs taken every two years, thus allowing comparisons to be made.
Predators: Possums, rats and feral cats
Operating since: 2007

I operate a trapping business for private properties, staff premises, commercial properties, holiday homes etc. I have around 50 properties that I trap on for mainly rats across Oban. I also target possums and feral cats when required. I trap for rats, possums and feral cats at the airstrip on behalf of Stewart Island Flights (as a volunteer) and also trap rats at Big Glory Bay at various Sanford farm sites and around their accommodation and through the bush at the head of Big Glory Bay.
Predators: Main targets are rats although I do trap for possums and feral cats as well.
Operating since: 2018

This committee is a group of ten people, elected annually at our February AGM. The main task of the committee is to administer the Tītī (Muttonbird) Islands Regulations 1978.
As such the committee:
Outside of the regulations we undertake work programs of pest management / rat eradication / pest plant removal, species management / enhancement, species transfers, etc.
We also advocate wherever possible with national and international agencies, whose activities may have an influence in one way or other, on the health and well-being of the Tītī and the other multitude of species that habitat our islands. As the objective we are aiming for is sustainable utilisation of the flora and fauna of those taonga islands, the same objectives apply to the ecosystem management externally, as these all have an influence on the health and well-being we are attempting to achieve.
The Islands that Rakiura Tītī Committee administer are those that were set aside at the time of the sale of Rakiura to the Crown in 1864. The argument at the time was that the Rakiura Maori never intended that those islands would be included in the sale of Rakiura! The Crown's way of appeasing the people was to set aside those eighteen islands, now known as the Beneficial Islands, as reserves for the sole use and benefit of named natives of the time and for their descendants. The other eighteen islands were also set aside under a different regime, these were known as the Crown Tītī Islands. They have also been set aside for the sole use and benefit of Rakiura Maori, however these islands require an annual permit to enter onto each year, whereas the Beneficial Islands are a descending right.
The title to both sets of islands were at one time held by the Crown, but now the complete ownership has been returned back to Rakiura Maori to manage under their own Rangatiratanga. Since this time we have seen major gains made with pest management, species management and with the support of the Department of Conservation, Te Runanga O Ngai Tahu, the University of Otago, etc.
These islands have at times been described as the jewels in the crown. We Rakiura Maori can agree with that sentiment as we go about doing tasks necessary to return those places back to as near natural state as we possibly can! The islands are 70% predator free now, and once we clear Rakiura of predators that keep invading our islands then we can complete our task.
Mo tatou, a mo ka uri a muri ake nei.
For all of us and our children after us.
We are actively enhancing the conservation values of the Rakiura Tītī Islands. We have undertaken eradications of all rat species from 70% of the islands and have intense rat control programmes for those islands in close proximity to Rakiura. Cats are prohibited. All Dogs have to have a permit to enter the Rakiura Tītī Islands. We are actively involved in biosecurity with strong policies and increasing rodent dogs checks in place each year. Our work includes the translocation of Taonga species within the various Tītī Islands. In addition to enhancing the conservation values we work to enhance the mana values of the Tītī Islands and its peoples encouraging the Matauranga values in connection to the whenua o Nga Tipuna.
Predators: All three species of rats
Operating since: Life time
Real Journeys in partnership with Rakiura Maori Lands Trust undertake rat trapping with A24s and Victor snap traps at Ocean Beach, the site of our kiwi viewing experience. Possum and feral cat control is planned to start in 2020.
Real Journeys have rodent bait stations and rodent traps at the Bluff ferry terminal and at the Bluff storage shed for freighted goods to Rakiura. ‘Nibble’ cards have been used to monitor presence of rodents. The ferries are checked weekly, during maintenance, for rodent sign and conservation dog Detector Gadget checks for rodent sign around six times per year.
Predators at Ocean Beach: Rats (possum and feral cat control planned to start in 2020).
Predators at ferry terminal: Rats and mice.
Operating since: 2017
Southland Ecological Restoration Network (SERN) is a network of Southland people “bringing back the natives”. The aim is to promote the restoration of native ecological sites in Southland.
Their website features a number of local restoration projects, with contact information and photos for each project. There is also at least one field day a year to bring people involved in restoration together, to encourage and share knowledge and also celebrate all the good work going on around Southland.
SERN openly invites volunteers to approach restoration project contacts if they wish to lend a hand.

The Port being on an island acts as a barrier to entry by pests. Bait stations are around perimeters of buildings which store edible product, There is a full Pest Management Programme in place which is MPI Compliant, as part of the RMP (Risk Management Programmes) for these areas. RMP stores, holding un-refrigerated products, have traps inside the buildings. All bait stations and traps are monitored at least monthly by an external contractor. Monitoring can be increased if necessary. The monthly reports/findings are reviewed by the Compliance Officer and feedback given to increase monitoring. Doors are kept shut unless in use for operational purposes to prevent pests entering. Buildings are monitored for any damage and if any occurs the area is mended as soon as possible. All staff are encouraged to report sightings of pests external to these areas.
Predators: Bait stations (external) and traps (internal) are targeting rats and mice.

Stewart Island Flights are trapping the Ryan’s Creek Airfield perimeter with victor traps around 150+ and working on more traps for another outer layer. At times they organise a reduction in deer numbers as well. We have been operating for in excess of 14 years. On the airfield we target rats and feral cats and on the 15 acres prior to the airfield (which we privately own) we have an good nature line of A12 possum traps and a few A24’s. DOC has mouse bait traps in both our hangars due to our Codfish flights.
Predators: Rats, feral cats, possums and occassionally deer
Operating since: Prior to 2003
