"Generally flying is amazing but being able to save people's lives at the same time ...
"Plus my office has the best view in the world. How could anybody not love it?"
Mr Dunham said the job came with its share of challenges too, including bad weather and being woken in the middle of the night and needing to be fly ready in 20minutes.
Trustpower TECT Rescue Helicopter pilot and base manager Liam Brettkelly said the trust did two and a half jobs a week on average and worked between Waihi and the far East Cape of the North Island.
In 2015 alone, the Trustpower TECT Rescue Helicopter saved or positively impacted the lives of 165 individuals, he said.
The majority of calls for the Tauranga-based helicopter included accidents involving motor vehicles, aviation accidents, incidents on farms, and incidents related to recreational pursuits.
As well as the two fulltime pilots, the helicopter also had four volunteers on call at all times, he said.
Trained as a motorcycle mechanic, Mr Brettkelly developed an interest in aviation over time, he said.
"Who doesn't love flying these things and helping people. Helping people is a huge part of it. Especially when they come up to you on open days like today and tell you their story and how we helped them however long ago."
Like his work colleague, Mr Brettkelly loved the view from his office: "On a nice day nothing beats that view down the coast, the water, it's absolutely beautiful.
"But I also like it when it's windy - makes the job a bit more challenging."
