The second Open to be played at The Hills finished yesterday and a third is scheduled for March 2010.
Beyond that, the future of the $US1.2 million tournament is unclear, but Mr Hill is in no doubt he wants it to stay at The Hills course.
He has poured money into the venue and to New Zealand Golf for naming rights but said there needed to be more capital investment at a higher level.
"If we can get some support behind us, from Government and council, we have the potential to make this one of the most significant events in the country," Mr Hill told the Otago Daily Times yesterday.
"We haven't had that support to this stage but there will come a time when decisions need to be made.
"Tell me a better venue.
''It would be perfect for this region to keep the event here."
Mr Tuohy said he was happy with the second Open played at The Hills despite significantly smaller crowds.
Attendance over four days was 24,071, down from about 32,000 in late 2007.
"That's great.
''We've had a lot of people come from out of town," Mr Tuohy said.
"Things are tough out there.
''It costs a family $100 to be here for the weekend and that's a bit of money."
Mr Tuohy's company is contracted to run the Open for New Zealand Golf at The Hills next year.
An extensive review of the tournament will be held in May and that may indicate how much longer it can be played at Arrowtown.
"It's not an indefinite thing," Mr Tuohy said.
"I think we could probably go five years, to be honest.
''That would be a pretty good haul."
It has been rumoured that Jacks Point, the plush new course on the banks of Lake Wakatipu, might bid for the Open but Mr Tuohy said that was unlikely.
"That's not a consideration right now.
"If we come to Queenstown, it will be to Michael's house."
Young American golfer Alex Prugh won the Open by three strokes from countryman Martin Piller after shooting 64 yesterday for a four-round total of 19 under par.
The tournament ended with another spectacular closing ceremony with a pipe band marching down the 18th hole and Sir Bob Charles arriving in a helicopter.
