Under the Chatham Islands Pest Management Strategy 2008-2018, Biosecurity Officers can enter land that you own or occupy and enforce the following rules:

Gorse Boundary Rule

RULE 5: Landowners and occupiers shall undertake an annual control programme to destroy all gorse plants prior to viable seed set within 15m of any boundary of the property where the adjoining land is clear or being cleared of gorse, or gorse on that adjoining land is being controlled to low density.

Gorse Reduction Rule

RULE 6: In areas of moderate gorse density (shown as Gorse Management Area 2 in Appendix 1), landowners and occupiers shall undertake an annual gorse control programme to destroy all gorse plants prior to viable seed set in areas of gorse that are less than 50 square metres in area.

Gorse Elimination Rule

RULE 7: In areas of low gorse density (shown as Gorse Management Area 1 in Appendix 1), landowners and occupiers shall undertake an annual control programme to destroy all gorse plants prior to viable seed set.

Operational Plan 2008

The Operational Plan 2008 outlines the budget and services that the Council intends to provide over the next 5 years to implement the Chatham Islands Pest Management Strategy 2008-2013.

The Strategy and Plan become operative as from 1 July 2008, subject to funding through the Annual Plan and Long Term Council Community Plan processes. Every year, the Operational Plan will be reviewed, and an Operational Report prepared to keep track of progress. Copies of the Plan can be viewed at or purchased from the Council.

The Chatham Islands is nationally and internationally important to biodiversity and nationally important to the marine industry. The Council is working with other parties involved in the movement of people and freight to the Chatham Islands to prevent pests new to the Chatham Islands from impacting on our economy and unique environment. The Biosecurity Strategy is a first step towards establishing an internal border between New Zealand and the Chatham Islands.
