Birds out of hand worth 20-odd in the bush
Clutch of kiwi brought back to mainland after island rehome proves too successful
The residents of an island in Northland are grappling with an unusual problem — they have too many kiwi. Seven kiwi captured near Waitangi, when their bush habitat was about to be cleared for pine forest, were released on to Moturoa Island in the 1980s.
Since then, kiwi numbers on the island, near Kerikeri Inlet in the Bay of Islands, have grown into the hundreds — and that has put pressure on the limited habitat and food available for the protected birds.
As a result, 21 kiwi caught on the island were released in O¯ pua State
Forest on Friday, easing the island’s population boom and boosting kiwi numbers on the mainland at the same time.
The operation would not have been possible even a few years ago but a massive pest control effort in O¯ pua Forest, which cloaks the hills behind Paihia, has made the area safe for the flightless birds.
Moturoa is owned by 21 families and has just a handful of permanent residents.
Landowner Karen Asquith said her father, Paul Asquith, retrieved the kiwi from Waitangi Forest when they were under threat from logging 40 years ago.
“We’ve watched them over the years grow in numbers, and I don’t think he ever imagined we might get to this point. They come stomping across the deck of the house and screeching at the window to say hello. They pop out during the day sometimes,” Asquith said.
“We’ve spent 40 years plus making sure that they’ve got a good habitat, we’ve set aside large tracts of marginal farmland, we’ve planted 60,000 native trees and we’ve dammed streams to create the right environment for them to thrive. We’re proud to give these back to the iwi now and see them go home.”
Asquith said there was “great debate” about how many were on the island, with estimates ranging from 100 to 300. A kiwi census is due to be held in July.
The operation to catch the kiwi started at 8pm last Thursday, with the birds so abundant the quota was reached by 11pm.
They were checked and weighed by vets, fed and placed in individual kiwi boxes in preparation for the journey to their new home.
Rough seas meant the original plan of taking them directly to the jetty at Waitangi had to be abandoned, with the birds instead taken to the more sheltered Windsor Landing in Kerikeri Inlet and from there by road to Waitangi.
The gifting and receiving of the feathered taonga was conducted by Bay of Islands hapū Ngāti Kawa, Ngāti Rahiri and Ngāti Torehina, led by Te Tii Marae chairman Ngāti Kawa Taituha.
They were then taken to five sites across the 2000-hectare Opua State Forest, from Kaipatiki in the north to Oromāhoe Rd in the south and released into pre-prepared burrows at dusk.

group Bay Bush Action has spent the past 12 years trapping pests such as stoats, possums, rats and feral cats.
Bay Bush Action founder Craig Salmon said Friday night’s release was the culmination of years of hard work, done in the hope of one day being able to bring back birds that were once common on the Bay of Islands mainland.
Salmon described the kiwi as “an incredible gift”.
“We will absolutely cherish these kiwi as much as we can. This is a very hopeful moment for the future of animals in Aotearoa.”
Salmon called on all those present at the release to spread the word that kiwi were back in numbers in the Bay of Islands bush and that their habitat had to be respected.
The group’s other founder, Brad Windust, said the 21 extra birds would boost the genetic diversity of the forest’s existing kiwi population.
They would also be “great for the forest” because of the important role kiwi played in the forest ecosystem.
The group’s project suffered a major setback last winter when roaming dogs killed at least six kiwi near Paihia.
Windust said that had spurred community members to donate a number of state-of-the-art AItechnology cameras, which could detect roaming dogs and instantly send out an alert.
The group took the dog threat very seriously, he said.
“We’re not going to get caught out like that again.”
Windust was among those given the chance to release a kiwi into its new home.
“It was amazing. I felt quite emotional holding it. He was named after a maunga here, Te Puke. He was nice and warm, he was beautiful. I felt very privileged,” he said.
The operation involved the cooperation of local hapū , island landowners, the Northland Regional Council, the Department of Conservation and community conservation groups Kiwi Coast, Bay Bush Action and Backyard Kiwi.
Kiwi Coast Mid North co-ordinator Andrew Mentor said 40 years of successful breeding on the island meant it was necessary to move some of the kiwi to a new location.
He believed the O¯ pua State Forest had about 40 kiwi prior to the release, so the local population had been boosted by about 50 per cent.
Mentor said he was confident the kiwi would be safe in their new home.
He said Bay Bush Action had worked hard on the dog problem since last year’s kiwi deaths, and the group’s traps were keeping predator numbers low.
“It’s been great to have this problem of too many kiwi on the island, and the time has now come to bring some of those kiwi home to where they originally came from.”
Karen Asquith, whose father originally brought the birds to Moturoa, was also given a chance to release one of the kiwi.
“She was pretty chilled. A nice big healthy female, 2.1kg, with a nice long beak. She just made herself at home pretty much straight away. She tucked in and had a snooze. She’ll go and feed herself later on.
“I think Dad would be very happy. I think we all are. It’s a great honour to give them back to where they came from.”
