Record-breaker Aaron Finch is relishing having fans in attendance when Australia face New Zealand for Sunday's Twenty20 series decider.

Finch hit 79 not out off 55 balls in Friday's series-levelling 50-run triumph to become his country's leading run-scorer in the format, with 2,310 overall.

His four sixes in the final over propelled his side to 156-6 and made Finch the first Australia batsman to reach 100 maximums in T20 cricket.

Finch was the only player who really got to grips with a tough surface, but he was just glad to help make it 2-2 after the tourists had fallen 2-0 behind.

"I've always said I'd rather get a duck and win than get some runs and lose," he said after New Zealand subsided to 106 all out, seamer Kane Richardson (3-19) the pick of the Australia attack as spinners Ashton Agar, Glenn Maxwell and Adam Zampa took two apiece.

"But to get some runs and contribute to a win is really nice. I felt like I was hitting them terribly for a large portion of the innings, but it was one of those wickets where you never really felt totally in, particularly when spin was bowling.

"It was nice to get a few out of the middle towards the end and get us to a decent total."

On the subject of a relaxation of coronavirus restrictions allowing for the return of fans for the final match, he added: "You play professional sport because you love entertaining, you love the atmosphere when you're at the ground.

"I love going to and watching sport, so to have fans at the ground, regardless of whether they're rooting for you or against you, is just brilliant. It provides so much."

Aaron Finch became Australia's record Twenty20 run-scorer with a captain's display as the tourists set up a series decider after a dominant victory over New Zealand in the fourth of five Twenty20 showdowns.

Finch's 79 not out off 55 balls helped lay the foundations for a 50-run triumph, with Australia posting 156-6 in Wellington before bowling out the Black Caps for just 106.

It means the series is now level at 2-2, with Australia having come from two down, and will be settled in the final match on Sunday.

Tim Southee was furious after Finch was given not out on umpire's call following an lbw review in the first over, with his reaction resulting in a formal reprimand for a Level 1 breach of the ICC Code of Conduct.

The fast bowler might have been even more angry had he known the damage Finch would go on to do, the skipper accounting for over half of his side's total to become his country's leading scorer in the format on 2,310 runs.

Finch smashed four sixes off the final over, that explosive spell alone giving him more runs than any of his team-mates, with Marcus Stoinis' 19 the next-best tally.

That fact underlined the tricky nature of the pitch and New Zealand could not get to grips with it as Australia's bowlers made hay.

Kane Richardson took three wickets, while Ashton Agar, Glenn Maxwell and Adam Zampa each contributed two, with Kyle Jamieson – who bowled that expensive over to Finch – providing the only real flourish on the Black Caps' scorecard with 30 off 18 deliveries.

With a thrilling finale in prospect, fans will be allowed to attend the decider in Wellington after a relaxation of coronavirus restrictions.
