Wellington kiwi chick makes fighting weight and hits a Capital Kiwi milestone

Featherweight by class, heavyweight by heart – a kiwi named Maui has made “fight weight,” meaning they have grown big enough to defend themselves against stoats. They have had their monitoring transmitter removed and they are now free on Wellington’s western hills.

Since 2018, The Capital Kiwi Project has partnered with locals, iwi and landowners – including Wellington City Council – to transform the hills surrounding our capital city into a place for kiwi to thrive in the wild.
 
Kiwi are tough and resilient animals. With predator threats controlled to appropriate levels our national icon and taonga can come home to the trails, reserves, and paddocks of Pōneke.
 
Over 200 kiwi are now free ranging out west around Mākara, translocated in over a dozen releases since 2022. A key goal for Capital Kiwi to create a growing sustainable population is to see chicks born in the wild and survive their early months when they're at risk of predation from stoats, so they can grow to a weight they can fend off that threat.
 
The most recent graduate, Maui, hatched on Terawhiti Station in October 2024. In March this year, they had their transmitter removed. 

“This liberation marks a significant milestone for kiwi comeback in the capital. In short: it shows that the network of protection Wellingtonians have woven together to welcome kiwi back home is working,” says Capital Kiwi project founder Paul Ward.
 
In areas with no pest control, kiwi chick survivorship is 0 - 5%. The main reason for this is the stoat - a wily mustelid introduced in the nineteenth century in a failed attempt to control rabbits. When adult birds die they are not replacing themselves with future generations, which means kiwi numbers could head towards the way of the moa with no animal predator control.

This is tragic because at around 1kg (after 6-8 months) a kiwi can fight off a stoat with their big, sharp raking claws. A big adult kiwi can fight off most all-comers and can live 40 or more years.

The purpose of Capital Kiwi’s 24,000 hectares stoat removal network is to give kiwi chicks a fighting chance to reach that mark.

To grow a kiwi population, a minimum of 20% of chicks need to survive. Capital Kiwi’s Department of Conservation permit target is for 30% of the first 20 chicks monitored (or six birds) to make it to 1.2kg.
 
Maui making fight weight is a huge milestone as it means the team have managed to hit their target from just the first seven birds! All 20 birds will have been monitored by mid 2026. 
 
“Maui was named by our ranger Rawiri because of his cheeky fighting spirit – he lived up to that ingoa (name) on the day: escaping the team’s slip cordon twice out on the Mākara hills," adds Paul.

By doing the work to remove pest threats and having people onboard as guardians of these precious manu, Wellington homegrown kiwi are a reality again for the first time in around 150 years. Go Maui!
