Organising committee chairman John Hart said building on the relationship with the Japan Tour was vital to the tournament's future.
The Open is not a fully co-sanctioned Japan Tour event but has a relationship that led to 14 Japanese professionals being included this week.
Eleven of those players made the cut, making for a pleasant series of meetings between Open organisers and people from the tour.
''They've said they are looking at building five tournaments outside Japan,'' Hart said.
''Even though we're not in co-sanction position, we're one of those five tournaments.''
Next year will be the third and final Open to be held in Arrowtown under the terms of the three-year deal Hart's committee signed with New Zealand Golf.
But there is no suggestion the tournament will be leaving.
''It's effectively a three-plus-five deal with New Zealand Golf. I don't think there's any doubt that we will be carrying on.''
It is expected this year's tournament will break even, or post a small loss.
Hart said the proof of the revived Open's growth was in the numbers. The 2014 tournament had revenues of $3.4 million and this year that jumped to $4.5 million.
''We're in a good fiscal position. The Government is obviously a key provider. We have that secured for 2016, and there are strong indications from the Prime Minister that he sees the Government staying in this for some time.''
The pro-am format is also here to stay, and cricket fans may also get to see the likes of Sir Ian Botham and Ricky Ponting again.
''They've been tremendous and the whole lot are saying they want to come back,'' Hart said.
''The feedback from all the players is that the tournament is something very special.
''The field is going to get stronger. The challenge for a tournament like this is never to get complacent. We need to keep growing.''
Organisers did not have a final figure last night but estimated crowds were similar to last year, when just over 18,000 people passed through the gates over four days.
