This is the 25th year of the event and Tasker is only the fourth person to receive the volunteer award.
Tasker (87), a retired motor mechanic, has volunteered at all 13 Masters Games in Wanganui since the first in 1989, and this will be his fifth time in Dunedin.
Later this year, he will be a volunteer at this third Pan Pacific Masters Games on the Queensland Gold Coast.
Tasker enjoys coming back to the Masters Games year after year.
''Enthusiasm keeps me coming back,'' he said.
''I like to meet up with my old mates again. I like meeting people and working with them and I like organising sports events.''
Tasker played bowls and was involved in organising the first New Zealand Masters Games in Wanganui in 1989.
He saw the Games gradually build up from small beginnings.
''I never had any inkling that it would grow so big. It was so small when it first started.''
''When we got sponsorship, it helped us out. We started getting T-shirts when the games got bigger.''
Tasker said the Games had been a success because they got older people out of the house.
''It builds their confidence and helps them meet other people to get different views on life,'' he said.
''Some people groan and grizzle because they have an ache and pain but some competitors overcome great odds and have a great outlook on life.''
Tasker has been impressed by the attitude of one of his best friends in Wanganui, who lost his legs in a shunting accident in 1948.
''He digs his own garden and does everything himself,'' he said.
''Some people moan because they have little aches in their legs but others are able to handle life through a disaster.''
Tasker said older competitors needed to use common sense when competing in the Masters Games and not get carried away by the competitive juices they had in their younger days.
''A mate of mine from Auckland, in his 80s, was competing in rowing, the marathon and half-marathon,'' Tasker said.
He told Tasker he had been runner-up to his main competitor so many times and was determined to beat him in the half-marathon.
''He wanted to beat him and get the gold medal. He didn't know at the time that his rival had collapsed on the course and died.''
Tasker, the president of Bowls Wanganui and a qualified bowls umpire, has won medals in bowls and Twilight 400 and believes they have a positive place in the Masters Games.
''I will be a volunteer again at Wanganui next year and I will be back in Dunedin in 2016,'' he said. He had positive advice for competitors at this year's New Zealand Masters Games.
''Participate and enjoy it. Meet new friends and look forward to meeting up with them again.''
