Mr Dawson denied speculation that the Chiefs could move to Tauranga or share time between the two cities. "We are certainly going to be staying in Hamilton."
The council signed an agreement with the Waikato Rugby Union in June, which is understood to include $50,000 a year in rent and a cut of ticket sales at the gate for a minimum of $100,000 and $85,000 for match day operating costs.
But the Chiefs deal has taken longer to settle as the two parties had been at least $20,000 apart over an annual rental agreement for the rugby facility.
"It's all progressing very well, it's just not 100 per cent finalised," Mr Dawson said.
"One issue is just around when we can play games there, it's more to do with the June window. Every year, Super Rugby stops because international games are coming in and we are finding out about the ability to have games in June."
The franchise was waiting on clarification from the Rugby Union over that issue.
"It's not so much the times it takes, it's important we get everything agreed."
Hamilton City Council community general manager Lance Vervoort said both parties had "agreed in principle" on the major points but said the discussions had been held up by the council's involvement in the Rugby World Cup and the Chiefs undergoing end-of-season reviews.
The council had agreed in June not to make any comment on either of the deals until both were completed.
Meanwhile, the Waikato Rugby Union is making plans to move from the Willoughby St office to the Waikato Stadium after the Rugby World Cup.
