The Chatham Islands is a beautiful part of the world and it is important that pests do not endanger our islands’ unique flora and fauna

Environment Canterbury(external link) is contracted to deliver biosecurity services on the Chatham Islands. Pest management is carried out in accordance with the Biosecurity Act 1993(external link) and national and regional pest management strategies.

Pests are most likely to arrive in vehicles, small boats, timber and machinery, especially agricultural and construction equipment – and with imported livestock, plants and general freight. Even commercial foods, fertilisers, grains and potting mix can contain pests.

We have prepared several fact sheets relating to pest management on the Chatham Islands, i.e. what to do if you are importing animals, plants or vehicles to the islands. You’ll find these at the bottom of this page.

Chatham Islands Pest Management Strategy

The two main goals of the Chatham Islands Pest Management Strategy [PDF, 10 MB] are:

  • Surveillance and control of pests already on the Chatham Islands
  • Border control to prevent news pest incursions

The Strategy is due for review in 2018.

Chatham Islands Biosecurity: A Snapshot 2011–2017

We co-produced Chatham Islands Biosecurity: A Snapshot 2011-2017 [PDF, 6.9 MB] with Environment Canterbury to raise awareness of the key pests that threaten our islands’ unique natural values.

The book provides a good summary of biosecurity activities on the islands over the last seven years and details our extensive joint work programme with Environment Canterbury.

It is a valuable resource for landowners, farmers and fishermen, enabling them to identify pest plants and animals and improve practices to help stop the spread of pests and protect our unique environment.

Chatham Islands Biosecurity: A Snapshot 2011–2017 will go a long way in informing the next version of the Chatham Islands Pest Management Strategy.

Remember to check, clean and dry all your gear when travelling.

‘No Pests Please’

Keep our islands unique. No pests please. Chatham Islands Council. No Pests Please is a border control programme for the Chatham Islands, developed in conjunction with SPS Biosecurity(external link).

It was developed in recognition of the fact that a variety of pests have already arrived on the Chatham Islands and caused significant damage, both to the islands’ ecology and economy.

It is essential that pests currently on the Chatham Islands such as possums, rats and hedgehog don’t spread to Pitt Island and other outer islands.

The impact on agriculture, the marine industry and the environment would be disastrous.

If you have seen a pest and are unsure what to do please contact us.

What you can do

Everyone travelling to or from the Chatham Islands is responsible for ensuring they do not bring pests with them.

You must:

  • thoroughly clean vehicles, camping gear, freight containers and machinery before arriving in the Chathams
  • make sure luggage and camping gear, etc. is free of stowaway pests; even boots, socks and clothing can carry unwanted seeds
  • do not bring plants onto the island without checking with the Chatham Islands Council whether they are pests
  • check supplies and equipment for signs of pests before travelling to the Chatham Islands
  • if you suspect that pests are being moved about or have established themselves, contact us
  • if possible, destroy or contain the pests immediately and then contact us
  • if you are moving within the Chatham Islands or travelling out of an area with a known pest problem, make sure vehicles, equipment and other material are clean.

Marine pests

Marine pests are most likely to arrive on boat hulls, in ballast water or in water intake systems such as sea chests.

They can also arrive as a result of fishing and harvesting activities or with marine equipment.

Marine pests include:

  • Asian clam and Asian date mussel
  • Chinese mitten and European shore crabs
  • Mediterranean fan worm
  • North Pacific sea star
  • caulerpa (a green seaweed)
  • undaria/Wakame (a Japanese seaweed).
