The TR Register NZ is a national car club and as such, the country is split into 9 Regional Zones, 6 in the North Island and 3 in the South Island. Like most car clubs in NZ each region organises its own runs, events and has regular get togethers, at various favourite watering holes, on agreed dates. These local events and meetings are displayed on the event calendar.
A few times a year, National events are run to draw members of different regions together, some of them are North Island events some of them South Island events. Once a year a National weekend is held, alternating between both Islands. These events are also displayed on the event calendar.
