The game format is four, 10-minute quarters with a two-minute break at first and third quarter and a three-minute break at half time.
Most teams play two games a day during the five days so fitness, energy and performance of coaches, players, umpires and other officials is put to the test during the tournament.
Within the UNISS area there are only seven netball venues meeting the criteria of a minimum of 18 courts to hold this tournament.
These include North Harbour, Auckland, Waitakere, Howick/Pakuranga, Papakura, Harbourside and Hamilton. For 2014, the UNISS will be hosted by Waitakere.
There are three grades, A, B and C and at the end of the tournament the top three teams from B and C grade are promoted to the higher grade for the 2014 tournament and the bottom three teams in A and B grade are relegated to the lower grade for the 2014 tournament.
In 2013 there were 32 school teams in A and B grade and 46 school teams in C grade, which is the entry point for any schools not previously entered in 2012.
The winners of the A grade was Mount Albert Grammar School, the winners of the B Grade Lynfield and the winners of the C grade Alfriston.
