Hart, who is the tournament's chairman, said Queenstown was the ideal place for the tournament and the golfers really enjoyed the week.
It was the 99th Open this week and the prize money had grown to $1.2million.
Hart said, ultimately, the aim was to get the prize money to $1.5million but that the event had to be sustainable.
''We are going to be terribly realistic right through this. We want to be financially sustainable long term so we will grow it when we can. We are not going to throw $2 million at it and then go broke,'' Hart said.
Ultimately, the aim was to include the Jacks Point course in the tournament but that might not happen for three years or more, Hart said.
The tournament would be based at The Hills next year.
He ruled out appearance money for players.
Queenstown was a great place to host the tournament and would continue to do so.
''Some of the Aussie guys say to me the one cut they don't mind missing is in Queenstown as they can stay here for the weekend. Queenstown is made for this tournament. You need two or three courses, you need the scenery and the close proximity.
''You couldn't do this anywhere else. It wouldn't suit Auckland.
''As long as we have got local support ... I can't see it moving. I hope it is here in 100 years but I won't be here to see it.''
Tournament director Michael Glading said New Zealand players were drawing crowds and the television rankings took a giant leap forward when Michael Hendry won the Open.
Golf NZ chief executive Dean Murphy said there had been thoughts about what to do next year when the Open brings up its century.
''Clearly, we need to formally celebrate it. Whether that comes from formal dinners and functions and that sort of thing. Obviously, that will be going on,'' Murphy said.
''We want all former champions that are still with us to come back and play or take some form of the tournament. If you look back at the field of champions which have come through the Open, it is a fairly impressive historical record of the game in this country.''
