Had a look at the programme covers site and it proved quite fruitfull. I have chosen to list all available dates for the various tracks, to not let any obscure race slip.
date | track | name of race | notes |
1985-10-20 | Manfeild | Benson & Hedges Saloon Car Series | B & H Series, round 1 |
1985-10-27 | Baypark Raceway | Benson & Hedges Saloon Car Classic | B & H Series, round 2 |
1985-11-17 | Pukekohe | Benson & Hedges Saloon Car Classic | B & H Series, round 3 |
1985-12-29 | Baypark Raceway | Coca-Cola Bottlers International Motor Races | NZTCC, round 1 |
1986-01-05 | Pukekohe | Mita Copiers New Zealand Grand Prix | NZTCC, round 2 |
1986-01-12 | Manfeild | International Motoracing | NZTCC, round 3 |

The Wigram race dated as 1986-01-xx very likely was held on 19th January 1986. And please note the spelling of Manfeild - it's not a mistake!
