New Zealand coach Dave Rennie said his team would be ⁠sticking to their expansive ⁠style at next year’s World Cup after ⁠the All Blacks thrashed the Wallabies for a second successive week with some sensational attacking rugby on Saturday.

Two convincing wins over Australia have got the New Zealanders back to winning ways after they lost a four-match series against South Africa 3-1.

Hong Kong will face both sides when they make their Rugby World Cup debut next year, playing hosts Australia in the tournament’s opening match on October 1 and then facing the three-time world champion Kiwis two weeks later.

The city side face Chile in their other Pool A match in between.

Rennie said that although the Springboks had ridden ‌a physical, conservative playing style to back-to-back World Cup triumphs, he remained convinced the tactics that put a premium on ball speed and width would be effective against it.

“There’s no point playing this way and then going to a World Cup and trying to play risk-free footy,” he told reporters after the 42-21 victory at Stadium Australia.

“We’re well aware you can put yourself ⁠under pressure the way that we’re trying to play, but we’ll also back ourselves that we’ll profit more than ‌we’ll suffer in those situations.

“I don’t think you want all the teams in the world playing the same game. I think if you look at the Wallabies, they’re ‌pretty similar to us. I think they’ll want to play, and it’s a point of ⁠difference, part of the ⁠DNA of both sides.

“If you want to just get into arm wrestles with a couple of the big sides in the world, it’ll ‌be a struggle,” he said.

Despite his team scoring six tries with some breathtaking rugby in the first half on Saturday, Rennie said there ‌were still ‌improvements to be made.

“We’re trying to grow our game, and we’ve got a long way to go,” ‌he said. “We just want to be able to play at a tempo that will test other sides.”

Australia coach Les ⁠Kiss called Australia’s performance “unacceptable” but said there was time to improve before the World Cup.

After a 50-19 thrashing in Auckland last week, Kiss was hoping his young side would bounce back in Sydney, but they were routed in a devastating first-half.

They conceded three tries in the opening 20 minutes and six in the first 40.

“Look, it’s unacceptable, 22 points like that, and you put yourself on the back foot, and the boys know that,” he said.

“It’s just not on. You can’t do that. We’ve had two bad halves now in the past two weeks, and it hurts you.”

The All Blacks tore the Wallabies defence to pieces, undoing a lot of the improvements seen since Kiss took over in July.

He had enjoyed five wins and a draw from his first six Tests before coming face-to-face with the All Blacks juggernaut.

Australia were missing some key players including fly-halves Carter Gordon and Ben Donaldson, and centre Len Ikitau, but it was nevertheless a sobering lesson a year out from the World Cup.

“You know a lot of young guys, single Test numbers, learned a lot tonight for sure,” said Kiss.

“But as a team I think there’s got to be a little bit more thinking about what it really means to actually turn up in that first-half and make sure we don’t make those errors that we did.

“We could have scored three times but we just didn’t work hard enough to get around the corner to score those tries. So there’s little things there that are just hurting us.”
