The 2021 NCL season will see the league’s 47 teams split into seven divisions based on region.
In lieu of the traditional structure, which sees 12 teams in the Premier Division, Division One and Division Two with 13 in Division Three, this has been done to ease players back into action after more than a year out.
The last NCL matches were in March 2020 before the season was postponed as a result of the coronavirus pandemic.
