A project to restore kokako in the Waikato is making progress.
Relocation of 20 birds at Mt Pirongia has been carried out already, Waikato Regional Council has been told.
As of early this month, there were now 12 male and eight female kokako on the maunga.
The finance committee, which approved an $110,000 contribution to the project's overall costs from the natural heritage fund earlier this year, signed off a formal funding deed last week.
Committee chair Jane Hennebry said it was good to hear of the project's successes.
"The natural heritage fund is designed to help other organisations undertake just this sort of environmental initiative and it's great to see the grant being successfully utilised as planned."
The project is being carried out by the Pirongia Te Aroaro o Kahu Restoration Society, which says it's had excellent volunteer support on top of agency funding.
