It will be the 13th Spring season competition in Hawke's Bay for the traditional winter code, dating back to the first in 2001 when administrators decided it was time to avoid clashes with club rugby, with many players wanting to play both codes.
This year, most adult Hawke's Bay union grades will end by August 10.
Tamati said current soccer fields at the regional sports park are to be transformed to rugby league fields, and it is hoped the finals will be played on the main enclosed arena in the William Nelson Athletics Precinct on October 12.
It's more than 25 years since rugby league had a regular single venue in Hawke's Bay, the Showgrounds in Hastings.
Tamati said he expected the Regional Sports Park move to be closely-watched, with the potential for it to become a permanent venue for the game, although it remains a hope the sport will eventually return to a winter season in the area.
Sports park chief executive Jock Mackintosh said the use of the park is "evolving," and needs of the different sports are changing.
This year it appears there is likely to be no more than a minor clash of the uses of the fields as a soccer season draws to a close and the rugby league games begin.
"If it all goes well there's no reason why it can't be a long-term move for rugby league," he said.
The league plans to send at least two adult-age teams to the national Maori tournament in Rotorua at Labour Day weekend, but has been otherwise concentrating on re-developing the code in the teenage grades during winter.
