There are around 150 schools which compete in secondary school rowing in New Zealand. Many of these school rowing programmes are based out of club rowing sheds, and many have grown so large they have their own facilities. Inter-school competitions occur regularly around the country, from small local regattas or challenges to the large national event known as the Aon Maadi Cup. The Maadi Cup is actually the prize given to the winners of the boys U18 eight event, which is the last event on the regatta programme, but the whole New Zealand Secondary Schools Championships has become known as the Aon Maadi Cup.
This regatta is one of the largest secondary school sports events in the Southern Hemisphere and is held alternatively at Lake Karapiro, near Cambridge, and Lake Ruataniwha, near Twizel. Age group categories are raced from U15-U18 in both male and female classes in a variety of boat types from singles to eights.
