In 2011 New Zealand Rugby announced what is the current format of the premier domestic competition in the country – the Mitre 10 Cup.
The Mitre 10 Cup for the last five seasons has consisted of two professional divisions, each consisting of seven teams.
The Premiership is the top division, with the winner being crowned the champion while the lowest ranked team is relegated to the Championship.
The Championship, essentially a second division, plays for the same named title.
All teams play 10 regular season games (five home, five away), followed by the Semi-Finals and Final.
Two Semi-Finals will take place between team’s ranked 1 v 4 and 2 v 3 in the Premiership and Championship respectively.
Each province will within this schedule play one double-header week, playing twice in a single round.
All Mitre 10 Cup Premiership/Championship teams play against each other once, as well as four crossover matches against Mitre 10 Cup teams from opposite divisions.
The teams in the Premiership division for 2018 are:
All games (including crossover matches) carry full competition points, four for a win, two for a draw as well as the bonus point format.
