Conservation Week series #2 featuring the North Island Kokako


Kaharoa Kokako Trust  (KKT) 1996-


The trust was initiated by Kaharoa residents, Peter Davey and Rachel Vellinga after learning of the declining population of Kokako in the area. Ecologist Carmel Richardson studied the Kaharoa Conservation Area, also known as Aislabie’s Block, Rotoehu and Mapara on contract from Dept. of Conservation.  Her work showed a marked decline in Kokako numbers due to introduced predators.

A Dept. of Conservation bid for funding to restart management in the area failed, this led to Peter and Rachel investigating options to assist. A group of interested people put together a proposal for volunteers to carry out pest control. This group decided to form a charitable trust as a guarantee that any donations would be used wisely and would be tax deductible. Thus the Kaharoa Kokako Trust was born.

Aislabie’s block is accessed off Kapukapu Road, via Kaharoa Road, it is bounded by three streams.   It was purchased by the Crown in 1984 to set aside as a reserve.  A Research by Management Experiment took place between 1990-1997 of Kokako populations at Kaharoa, Rotoehu and Mapara.

Predator control took place for 3 years at Kaharoa, no controls in Rotoehu then the pest controls were rotated for a further 3 years, and during this time the Mapara Block was not touched.  The study showed that the introduced predators of rats and possums were the greatest threat to the Kokako birds in these areas.  Pest eradication was proven to be the best method of ensuring Kokako do not become extinct in the region.

The KKT then sought funding to purchase 130 bait stations which volunteers would place throughout the Kaharoa Reserve. Monitoring of the bait stations would be handled jointly by volunteers and DoC workers.
