Mr Vincent said it was hard to compare statistics from year to year because it was different people, different situations and different weather involved.
"But, isn't it great that we flew these missions and, hopefully, the statistics mean people are being more careful on the roads and while enjoying their summer activities."
He said he couldn't put his finger on why there had been fewer missions this year but he was taking it as a positive sign.
"We have had a wide range in tasks, no matter how careful people are, accidents are still going to happen and we are there to help."
The chopper's operational costs were $1 million a year and more than 50 per cent of that was funded by the community.
