Great Britain Lions are scheduled to challenge the PNG Kumuls in 2019.
This follows approval by the Rugby League International Federation for a Great Britain tour to the southern hemisphere next year.
The last time the Great Britain national rugby league team, nicknamed the Lions, competed was in 2007.
This was when the decision was made to focus on England, Wales and Scotland as separate sides.
Though there is still some discussion to complete on 2019, Ralph Rimmer, chief executive of the Rugby Football League, says everything looks to be moving in a positive direction.
The tour, which the Rugby League International Federation board says is subject to consultation with the major playing leagues and the players' representatives, is part of an eight-year rolling contract approved in principle at the end of a four-day summit in York.
The Lions will not meet Australia, who will tour England in 2020, but will play matches against New Zealand, Tonga, Samoa, Fiji and Papua New Guinea.
The International Federation further unveiled plans for a two-division Oceania Cup in 2019, with Australia, New Zealand and Tonga playing in one group and Samoa, Fiji and Papua New Guinea the other.
