Thank you for your Of icial Information Act (OIA) request to the Department of Conservation,
received on 14 March 2023 in which you asked for information related to Pūkaha Mt Bruce.
Your questions and our responses are listed below:
1.
Pukaha’s 2021 Annual Report states that there are 6 pairs of kiwi in the Pukaha
Forest. Can Pukaha Mt Bruce staff account for any of the other 148 kiwi which have
been bred at, or brought into, Pukaha Mt Bruce since 2003? If so, how many and
where are they?
The Department is unable to provide the requested information as these details are held by
Pūkaha Mt Bruce, and we recommend they are contacted if this information is required. This
part of your request is therefore refused under section 18(g) of the OIA as the information is
not held by us, and we have no grounds for believing another entity subject to the OIA has
the information.
2.
How many kiwi were hatched at Pukaha Mt Bruce in the past 12 months (bred at
Pukaha, not hatched for other organisations) and how many kiwi have died at Pukaha
Mt Bruce in the past 12 months?
Please refer to the response for question 1.
3.
The Pukaha Annual Report states that predator numbers are increasing (ferret
numbers up 47% to 88 and feral cat numbers up 59% to 268). With this in mind, are
kiwi stil being released into the Pukaha Forest (and if so, how is this justified?).
Please refer to the response for question 1.
4.
Why is the myth that kiwi, once they meet the target of 1.2kg are 'capable of fighting
off predators' stil being perpetuated by DOC and Pukaha Mt Bruce when so many
adult kiwi have died there?

The 1.2 kg refers to the recommended weight to release juvenile kiwi, as stoats continue to
be a primary predator for kiwi. Young kiwi are vulnerable to stoat predation until they reach
approximately 1 kg in weight (about 6 months old), at which time they can usually defend
themselves from stoats and cats. The recommended release weight of 1.2 kg provides a
weight buffer to increase survival rates from stoat predation.
Kiwi of any weight or age are susceptible to predation by both dogs and ferrets.
Please note that this letter (with your personal details removed) may be published on the
Department’s website.
