Press Release: Pukaha

We are delighted to let you be the first to know of the hatching of a white kiwi chick at Pukaha. As far as we know this is the first hatched in captivity and definitely the first hatched at Pukaha. This exciting event marks the end of the most successful kiwi breeding season in Pukaha’s history with a total of 14 chicks hatched.

The all-white chick is not an albino but the rare offspring off kiwi that were transferred from Little Barrier Island to Pukaha in May last year. The intention of the transfer was to increase the kiwi gene pool and grow the population in the long-term so we are delighted with this great result. The chick is a North Island Brown kiwi that is white.

Local iwi and Pukaha Mount Bruce partner, Rangitane o Wairarapa, has named the chick Manukura which means chiefly status. Rangitane chief executive and Pukaha board member, Jason Kerehi, said tribal elders saw the white chick as a tohu or a sign of new beginnings.

“Every now and then something extraordinary comes along to remind you of how special life is. While we are celebrating all 14 kiwi hatched this year, Manukura is a very special gift.”

Your chance to see Manukura in our kiwi house

Manukura will be in the kiwi nursery until the end of May where you may view it being weighed daily at 2.00pm. It will remain in captivity with our other chicks for at least four to six months and there will be the opportunity to for regular viewings while it is being cared for. The health and safety of this very special chick is our priority.

Please feel free to phone ahead to make sure it is available. We would love to see you.

Kiwi recovery programmes are proving their worth even though the national population of the threatened bird continues to decline, Conservation Department science officer Rogan Colbourne says.

Mr Colbourne has been part of the BNZ Operation Nest Egg scheme. The Hawke’s Bay group released its 100th young North Island brown kiwi into the Kaweka Ranges on Thursday.

Nationally the kiwi population is thought to be falling by about 6 per cent a year, but Mr Colbourne said local programmes were making a difference, in some cases having increased the local population.

“At Okarito [on the West Coast] they have increased the population from 150 to more than 300,” he said.

In Hawke’s Bay, with a kiwi population of fewer than 1000, the addition of 100 young birds since 2003 was significant. Kiwi lived on average to 40 – and even to 60 – if there were no predators.

In these programmes, eggs are taken from the wild and incubated, then the hatchlings are kept in a predator-proof environment till considered big enough to fend for themselves in the wild.

“There is a 90 per cent hatch rate with these eggs, compared with only 50 per cent in the wild, for various reasons,” Mr Colbourne said.

“Possums can eat the eggs, the adults can damage them accidentally, and there can be bacteria after rainfall.

“Once hatched [in captivity] about 80 per cent reach the sub-adult stage and once they are released about two-thirds survive in the wild, though that varies from area to area.”

Of kiwi hatched in the wild, only about 5 per cent survived to become adults, as predators such as stoats, ferrets and feral cats ate the young birds. Ferrets and dogs could kill adults, and dogs were a particular worry in Northland.

About 15 recovery groups were operating in the North Island, with assistance from DOC and other organisations, Mr Colbourne said.

The Hawke’s Bay group is led by the Environment, Conservation and Outdoor Education Trust.

Spokesman Alastair Bramley said the survival rate for the kiwi released in Hawke’s Bay was about two-thirds overall, but it had been up at 90 per cent till an outbreak of ferret attacks in 2008.

“We haven’t lost any since then,” he said.

Dogs were not such a big problem in Hawke’s Bay because hunters there had to put their dogs through kiwi aversion training before they could register them, Mr Bramley said.

The 100th kiwi has been named Parauri and was released in the Kawekas after a ceremony at the Pan Pac Kiwi Creche, inland from Tutira.

Press Release: NZ Plant Conservation Network

Climate change increases value of Kiwi native plant

The golden sand sedge – pingao – has won the New Zealand Plant Conservation Network’s 2009 favourite plant poll, and could be a valuable defence against climate change effects.

The pingao topped more than 100 species in the annual poll. Network President Philippa Crisp said that pingao would become increasingly important in combating the effects of climate change, particularly as an increasing number of coastal homes came under threat

“If the global plan to fight climate change stalls and sea level rises occur, pingao will become even more important to New Zealanders because it plays an important role in stabilising sand dunes and creating a beach contour that is not so vulnerable to storm events and sea level rises,” Dr Crisp said. “Pingao may be our only sustainable hope for coastal protection”.

Dozens of rare West Coast kiwi may be moved away from their ancestral homes to islands in the Hauraki Gulf and Foveaux Strait in a desperate attempt to save the species from extinction.

The Department of Conservation says it has to create back-up populations, away from stoats, to avert extinction.

Although some Haast and Okarito Rowi kiwi chicks are already raised away from predators, they are returned to their home forest in South Westland when they are large enough to fight off stoats.

Under new proposals, DoC wants to move breeding pairs of Okarito birds to the sub-tropical Motuihe Island in the Hauraki Gulf, near Auckland, and up to 10 Haast birds to Rarotoka Island, in Foveaux Strait.
