"Chopper country extends from our rugged mountain ranges and sweeping coastlines to right over the back fence," he said.
"Whether it's a medical event on a ski slope or a crash on a bike trail just down the road, choppers are there for Kiwis when something unexpectedly goes wrong.
"It's comforting to know that help is close by, no matter where we are. That's why we're proud to have partnered with the choppers for more than 35 years."
A total of $1.22 million was raised last year and the goal is to beat that in 2019.
The 15th annual Westpac Chopper Appeal is supported by fundraising activities in schools and community centres, as well as a nationwide street appeal on Thursday, May 9.
Westpac funds the marketing and administration costs of the appeal and distributes all of the funds raised back to the rescue helicopter trust of the donors.
You can visit the chopper appeal website to donate, as well as visiting your local Westpac branch or by texting your postcode to 2449 to make a $3 donation.
Westpac is the principal sponsor of the Auckland, Waikato, Wellington and Canterbury Westpac rescue helicopters.
The annual Westpac Chopper Appeal helps raise funds for all regional rescue helicopter services around New Zealand.
