Molesworth Station

Molesworth Station

New Zealand’s biggest farm, the 180,787 hectare Molesworth Station, is part of a vast, mountainous landscape in the northern South Island high country. It is one of the last large farmed areas where possums and other vectors of bovine TB are still being brought under intensive control.

Molesworth is the focus of a nine-year programme of targeted possum control and wildlife surveillance, beginning winter 2017.

This large high-altitude property was originally excluded from the official pest control programme under previous National Pest Management Strategies that were initially focussed on the reduction of infected herds.


The Molesworth Station TB eradication strategy includes TB testing, monitoring wildlife infection indicators, and implementation of a rolling pest management programme.

Three updates each year keep interested communities abreast of progress and developments.
