I remember the 8 lane track at Rongotai College I help load it up from the Boys Brigade in Wainuiomata around 1971. Previously we use to race at Le Mans, the dodgy place upstairs off Manners Street in Wellington which was 1/32 scale. There was another 1/32 track and drag strip called Malibu Raceways in High Street Lower Hutt run by Trevor eve who use to race a 1650cc Allcomer Anglia. Then International Raceways set up two 1/24 tracks in Wakefield Street and a further track in High Street Lower Hutt. It was the death of the two commercial 1/32 tracks in Wellington.
Still have some remnants of the early 1/32 a 1/24 era.
