Local hero Ryan Wood has secured Toyota's first Supercars win, holding his nerve against challenges from a host of established stars during a thrilling race in New Zealand.

After championship leader Brodie Kostecki cantered to victory from pole in the first race of the Taupo round on Saturday, proud Kiwi Wood hung tough as Broc Feeney and Chaz Mostert pressed to knock off the pole-sitter.

Mostert briefly claimed the lead from Wood, before the emerging star again hit the front with seven laps remaining.

The 22-year-old's second career win came ahead of Feeney and Mostert who shared the podium with him.

Wood was ecstatic when taking the chequered flag, embracing with Supercars legend and fellow New Zealander Greg Murphy.

In just their ninth race, Toyota achieved their first win quicker than any other manufacturer in Supercars history.

"I'm so incredibly proud of our team and what we've done with this beautiful car," Wood said.

"To win in our third round is pretty special.

"Sorry about all my emotion, it just means so much to do it at home in front of so many friends and family and supporters of mine."

Wood and his Walkinshaw team will be able to thoroughly enjoy the victory, with all racing on Sunday cancelled due to a looming cyclone on the North Island of New Zealand.

Cyclone Vaianu is expected to make landfall earlier than expected, meaning the third race at Taupo - and 10th of the season - will now go ahead next weekend in the historic round in Christchurch.

"This is an unprecedented situation that has never occurred in the history of the Supercars Championship," interim Supercars boss Barclay Nettlefold said.

"It's very disappointing to see a weather event of this scale disrupt what we had hoped would be an exciting final day of racing.

"We deeply regret the impact this cancellation has on our fans who have travelled to Taup? to be part of this event.

"But a cyclone of this intensity leaves no other option, and the safety of everyone at the circuit has to come first.

"We're delighted to be in a position to make it up to fans and all our partners, by adding a race to the Christchurch event."

Dick Johnson Racing's Kostecki, who has endured mixed fortunes since his 2023 title with Erebus, has four wins from the first nine races of the season.

Kostecki will take a slender championship lead over Feeney to the South Island of New Zealand when racing resumes on Friday.
