The forest had been the site of major predation events in the past, most notably in 1987, when a dumped dog was thought to have killed hundreds of kiwi over a six-week period, but numbers had bounced back since then, helped by pest control work carried out by hapu-led community group Iwi Kiwi and Northland Forest Managers.
The 2200ha Waitangi State Forest and the adjoining 570ha Waitangi Endowment Forest were a model of how plantation forestry and kiwi could coexist, Mr Walker said.
On September 1 an adult male kiwi was attacked by a dog as it was being walked along a road at Kaeo. The bird was still alive when it was taken to the DoC office in Kerikeri, but was so badly injured that it was euthanased.
A possum hunter was spoken to by DoC this month after a leg-hold trap left on the ground caught a kiwi near Russell, and a bird was run over at Dove's Bay, near Kerikeri. It survived, and is being cared for at the Whangarei Bird Recovery Centre. It was one of 70 kiwi hit by cars in the Dove's Bay/Rangitane area since 2000, Mr Walker said.
* If you have information about the Waitangi Forest kiwi death, or see a dog in the forest, call DoC on (09) 407-0300 or Northland Forest Managers on (09) 407-7115. After hours call the DoC hotline (0800 DOC HOT).
Dogs are not permitted in the forest without a permit.
