The 2009 Air New Zealand Cup was a provincial rugby union competition in New Zealand, which was run as a round-robin tournament from 30 July to 25 October.
There were 13 rounds where every team played each other once.
The top four teams on the Air New Zealand Cup table advanced to the semi-finals, where they played for a chance in the Grand Final.
Most weeks, one game was played on Thursday at 19:35 (NZ Time), two games on Fridays both starting at 19:35, three games on Saturdays at 14:35, 17:30 and 19:35 and one game on Sundays at 14:35.
Again, this is most common, there were games played at 16:30 or 18:30 and more or less games played on certain days, e.g. Thursdays and Saturdays.
