The following year, in 1979 the pair had an even more dominant win, with a record-breaking six-lap margin to their nearest rivals. Just after taking over the car Richards had to drive through treacherous conditions with half the track wet and half dry. He and Brock subsequently took the car back to New Zealand for the end-of-year summer series. For the 1980 race, Brock was now leader of the Holden Dealer Team, in the first year of the new Holden Commodore. Early on in the race, Brock made an uncharacteristic error colliding with a back-marker while lapping it. After a strong comeback drive Brock got back into the lead before handing over to Richards who then drove matching lap-times to take a hard-fought third win.
