England fast bowler Steve Finn says he and his fellow bowlers will stick to their basics for the third T20 against New Zealand, trusting they will be able to do the job and win the series.

The sides are tied at one game each, after the Black Caps won the second game in convincing fashion. Both games were high-scoring, and Finn thinks the finale at the Westpac Stadium on Friday.

Finn said: "Our basic principles were the same ... we just have to make sure we nail our plans and skills. That's when we'll win games of cricket.

"It's certainly going to be an exciting end to the series. We've played some good cricket at stages throughout the two games - excellent in the first and then at times in the second.

"We're ready for the game tomorrow, and it will be good fun."

The paceman also said he wouldn't be concerned by some aggression in the middle, given Kiwi bowler Mitchell McClenaghan's penchant for riling up the England players, adding: "If they want to be more aggressive, that's not something that fazes us ... we concentrate on what we want to do."

Of his own performances, where he took three wickets for 72 runs in the first two games, Finn added: "As a bowler, you have to find ways of not leaking runs.

"That's part of the challenge of the series, and I've enjoyed it so far. I went at about 10 an over in the first game. But we won, so I was happy.

"The other night, I thought I bowled all right apart from a couple of balls I probably got wrong at the wrong stage of the innings. But that happens in Twenty20 cricket.

"I'm happy with where I am at the moment."
