The main feature of the year was the National Competition, run by the New Zealand Rugby League.
The New Zealand national rugby league team played an end of season test match against the Australian side, before they toured Great Britain and played a three match test series against the England team.
The same four teams as 2017 will contest the National Championship, after Counties Manukau won the 2017 promotion/relegation game.
The Warriors will also fielded teams in the Intrust Super Premiership NSW and its associated under-20s competition.
During the 2018 NRL season, Auckland's Mount Smart Stadium will host a double header on 7 April where the Warriors will play the North Queensland Cowboys and the Wests Tigers will play the Melbourne Storm.
