Ryan Fox, Mike Hendry and Josh Carmichael would be the only "name" pros not attending this year, Gillespie said.
"Most people will know that Ryan's doing great things in Europe. Michael's currently in Japan and Josh is there caddying for him.
"Josh won our event in its first year but apart from Ryan, Michael and him, we've got a very strong field."
Starters include Daniel Pearce, Brad Shilton, Troy Ropiha, former Wanganui golfing brothers Simon and Craig Owen, and Nick Gillespie. NZPGA president Susan Farron will be another starter.
Gillespie is hoping the weather gods smile kindly. Last year the event was abbreviated when gale-force winds made the course unplayable.
"The greens and course are in great nick, bearing in mind the sort of weather we've had in last couple of months."
While the pros will play for $20,000 in prizemoney, there are exceptional prizes for the amateurs.
"We've got regular teams of amateurs, supported by the likes of Craigs, Balance Chartered Accountants and Sewell and Wilson, so we have great support from the local community.
"There's more locals than outsiders playing in it but we're always trying to make it bigger and better."
Gillespie said that at 3pm on Thursday, September 3, PGA teaching professional Scottie Hill and other professionals would run a clinic for "anybody interested in learning how to play golf, basically".
