For sponsorship reasons, the competition was known as the ITM Cup and it was the fourth season under the lead sponsor.
If necessary of a tiebreaker, when two or more teams finish on equal points, the union who defeated the other in a head-to-head got placed higher.
In case of a draw between them, the side with the biggest points deferential margin got rights to be ranked above.
If they were tied on points difference, it was then decided by a highest scored try count or a coin toss.
The top two division winners, based on table points, received a home semi-final.
The competition started on Thursday, 15 August, with Counties Manukau taking on Wellington at ECOLight Stadium.
