The Auckland Rescue Helicopter Trust said it has no option but to head to court today over its funding.
The trust is challenging a decision by the Auckland Council-controlled Regional Amenities Funding Board to cut its funding by $750,000 over two years.
It said the trust does not need the money as it has been so successful at fundraising.
Helicopter trust chair Murray Bolton said all others wanting funding have received an increase over the past six years while their funding has continued to drop.
"We think we're being treated unfairly by the Regional Amenities Funding Board, and there's no other recourse we have other than to challenge how they're treating us in the court."
