It would also bring rare commercial opportunities for the NZRL, who have struggled to generate income.
The Kiwis haven't faced their transtasman rivals in a stand-alone series since the late 1990s, although they have met on multiple occasions within one year under the Tri Nations and Four Nations formats.
But the NZRL's optimism needs to be accompanied with a note of caution, as the NRL have a history of making the right noises and then doing, well, almost nothing.
The 2015 centenary Anzac test was all but confirmed for New Zealand before being yanked away at the last minute with a cursory explanation.
And, during the negotiations of the current broadcasting deal, the NRL "forgot" to include a provision for test matches in New Zealand, claiming their hands were tied because of the commercial arrangements.
But there are signs of hope.
The Australia Rugby League Commission have talked about a greater emphasis on the international game and Kangaroos coach Mal Meninga is a vocal advocate for test football.
The ongoing competitiveness of the Kiwis means additional tests will be money-spinners on both sides of the Tasman.
"It will change from 2018 because we'll have a new broadcast agreement that will change that," ARLC chairman John Grant told the Herald on Sunday earlier this year. "It should be a home-and-away-based series. That's what should happen."
Hayton expects the international calendar will be confirmed in the next six months.
