Tournament director Ian Nicholls said it was a significant tournament for the over-55 age group of golfers.
"The tournament is open to men and women, with a field of 136 with 96 men and 40 women representing 62 New Zealand clubs," he said.
"There are six divisions of 16 players in the men's. In the championship division, the lowest men's handicaps vary from Peter Rankin on 3 from the Royal Wellington Golf Club, closely followed by Ron Sisson from Omanu on a 4 and Alan Spedding from Te Puke on a 4.
"Mount has six players in the top division with Andrew Markman (5), Phil Maddren (5) the lowest handicappers."
The men's format is 18 holes of strokeplay on Monday afternoon to qualify, followed by four mornings of matchplay from Tuesday to Friday to find the champion.
The women play gross, nett and stableford over four days with Wednesday a day off.
Nicholls said the course at Mount Maunganui would be in top condition and set up fairly for the golfers.
"Our course superintendent has got the course exactly where he wants it. We are not going to make it a fiery course or anything like that. It is just going to be a good, competitive course I think.
"You can never quite tell what the winds and sunshine are going to do to the sand-based course so we are trying to keep it a good, playing course."
