Heading into the final 37.34km Argyle Rd/Raukawa Rd stage on the way back to Havelock North former Targa New Zealand event winners Dippie and Grant, from Dunedin, enjoyed a 3 min 20.7 lead over Kirk-Burnnand and Hay.
But, with Dippie looking odds on to stay on top with just minutes to go, he "had an off", leaving Kirk-Burnnand to claim top spot with a winning margin of a minute and a half.
Dippie and Grant were not the only high-profile pair to end their event off the road.
Earlier in the day top local pair Ivan Knauf and Trevor Corbin (Subaru Impreza WRX) crashed out of fourth place on the very first stage from Waimarama back to Havelock North, while later on Tauranga pair Simon and Sita Clark (BMW M3) lost what looked like a sure spot in the top six with a similar car-bending off in the fourth stage.
One of the pre-event favourites, Mitsubishi Evo 9 pair Jason Gill and Duncan Robinson, from Auckland, didn't even make it that far, their event ending with a roll on Saturday.
In fact the make-up of the final top 10 bore little resemblance to that at the end of the first and second days.
