"I am very privileged to be supporting the Northland Rescue Helicopter service because the work they do is amazing," Hamill said.
"It has been said by many people before but you just never know when you might need the service and I am looking forward to taking part in some of the activities during the 2018 fundraising appeal."
Northland Rescue Helicopter General Manager Vanessa Furze said the service is thrilled to have Hamill on board.
"We are so well represented by our ambassadors and they really are very important to helping raise the awareness of our need to raise funds to meet operational shortfalls over the busy summer months," Furze said.
"Those public donations are just as crucial as the sponsorship we receive from Northpower ($100,000 annually) and Top Energy ($50,000 annually), plus all of our other sponsors, supporters – and of course the generous funding and ongoing support we receive from the Northland Regional Council."
The Northland Rescue Helicopter Service has flown more than 20,000 missions since 1988 and has been instrumental in saving thousands of lives. In 2011 the service completed 581 jobs compared to 901 in 2017. The flight tally for 2018 has already reached 718.
