Grass-tracks seemed to come and go with some regularity. ISTR an 'auto-cross' type venue at the Aitkenhead Sawmill location on the Pokeno-Thames Rd. and another venue over the Waikato, from Tuakau----in the Pukekawa/Onewhero area. This was basically circular where 'races' were held..a sort of 'red-neck....run what you brung" type activity.
