The founder of Life Flight is being remembered in Wellington today, 30 years after his untimely death while helping a police mission.
Peter Button is credited with helping more than 30,000 people by starting Life Flight, which he was inspired to create after his horror at watching the Wahine sinking.
Despite rescue efforts, 53 people died when the ferry sank on April 10, 1968. Watching from the shore, Button vowed to a friend that he would find a better way.
It took him seven years to learn to fly and launch New Zealand's first ever dedicated rescue helicopter service, with Life Flight officially starting in 1975.
His legacy will be honoured today, on the 30th anniversary of his death, at a 3pm service in Wellington.
"What is here today is what he always wanted it to be. He would be so proud to see it doing exactly what he envisaged."
When Peter died, thousands lined the streets of Wellington for his funeral, and helicopter pilots flew overhead.
Clive Button said he was always surprised and touched by how many people wanted to pay tribute.
"He just did the job he did, and didn't expect anything other than that.
"We didn't actually realise how many people it touched. That day [in 1987] was like being in a bubble, we couldn't believe what was going on.
"We were only planning a small event, and then it just kind of took over."
Life Flight Trust chairperson Annette King said Button was the heart and soul of the helicopter rescue service.
"We are remembering him, around his family and friends, and some of our civic leaders.
"It's our way of acknowledging, and continuing to acknowledge the work of Peter Button.
"His work was incredibly important. When we look today, all these years on, at the vital work our air ambulances carry out, there'll be many people out there whose lives have been saved, and know how crucial it is to have such a service.
"We should always remember those who have built such institutions for us."
Button died in 1987, only two days after receiving a Queen's Gallantry Medal for a daring rescue the year before.
He was flying the rescue helicopter on a police mission when the helicopter hit power lines, with the crash proving fatal for all on board.
