Hazlewood opens up on 'one-off' outburst

A contrite Josh Hazlewood has opened up about his meltdown during the recent Test in Christchurch, saying it was out of character and won't happen again.

Australia paceman Hazlewood and skipper Steve Smith were both charged with dissent and fined during New Zealand skipper Brendon McCullum's farewell Test.

Stump microphones picked up Hazlewood swearing after an unsuccessful review on day four.

Hazlewood says the outburst had more to do with a wicket-less morning session than anything else.

"It wasn't really towards anyone, it was just venting a bit of frustration," Hazlewood told AAP.

"It was definitely out of character. I can't ever recall doing anything like that.

"It was just one of those heat of the moment things. We'd had a tough session with a couple of near misses.

"In the future I have to be a bit smarter ... I have to behave better."

Hazlewood added the incident, which came as Australia marched towards a 2-0 series win that delivering the No.1 Test rankings, was "definitely a one-off".

Coach Darren Lehmann will certainly be hoping so, having made his thoughts on the matter clear to Hazlewood.

"I got a little bit from the coach afterwards," Test spearhead Hazlewood said.

"Boof said 'you've just got to realise the microphones are on all the time, realise where you are and what you're saying'.

"We're well behaved for the majority of the time and there is the odd slip-up.

"We've got to be better and hopefully they happen less and less in the future."

Hazlewood also gave NZ allrounder Corey Anderson a spray shortly after the incident.

The two sides will meet in the ICC World Twenty20 on March 18 but the pair have already shared a beer and a laugh about Hazlewood's blow-up.

"I know Corey quite well from the IPL, I was just trying to get under his skin a little bit," Hazlewood said.

"What happens on the field stays on the field, we're great mates off it so it's all good. The Kiwis are a great bunch of blokes."

Australia will look to tighten their grip on the No.1 Test ranking when they tour Sri Lanka in July.

"We really enjoyed those few weeks in New Zealand and had good success," Hazlewood said.

"There's no Tests for a while now, so we can hold that No.1 ranking for a little bit and let it sink in."
