Only two teams, Auckland and Canterbury, haven't competed in the Championship tier. Northland and Otago, on the other hand, have both participated in the Championship each year. Only one side, Hawke's Bay, has won the Championship more than once, their 2020 victory adding to their 2011 and 2015 successes. Of the twelve teams that have participated in the Championship, there have been eight different winners. With the exception of Taranaki in its final season, no Championship team has ever won each of its four crossover matches in a single season.
