The New Zealand Tourist Trophy Race - for Motorcycles was first run in June 1931 on Waiheke Island.
The roads used were a 6 and 3/4 mile circuit starting in Ostend and running through Onetangi back over the hills above Palm Beach and down to Ostend.
Roads used were Ostend Road - the start, to Onetangi Road, hard left turn into Sea View Road and up over the hills between Onetangi and Palm Beach back to Ostend Road

Waiheke was used from 1931 to 1950 [ a break from 1941 until 1946 because of the War ] and after 1950 went onto the Mainland, at Seagrove, a circuit at Mangere and later Pukekohe.
