Sam Cane is excited by what the future could hold for New Zealand after they dished out a record-breaking hammering of Australia to retain their firm grip on the Bledisloe Cup.

The All Blacks hammered their trans-Tasman rivals by the biggest ever margin at ANZ Stadium on Sunday, starting the Tri Nations series with an emphatic six-try drubbing.

Richie Mo'unga scored a first-half double and finished with 23 points in a victory for Ian Foster's side that gave them a 2-0 lead over the Wallabies with one Bledisloe Cup match to play,

New Zealand have not lost a Bledisloe Cup series since 2002 and captain Cane believes there is more to come from his side after a brutal demolition of Australia.

The flanker said: "It's a pretty happy changing room in there at the moment … just filled her [the trophy] up. The trophy is really important to us, and we care a lot about it.

"I'm just so proud of the work we’ve put in over the last five-six weeks building up to this moment. It feels like we’ve improved every single week and I'm really excited about where this group can go.

"They're a tough side. There will be areas they'll be happy with and there will be areas they're not. One thing I've always admired about the Aussies is the way they pick themselves up. They'll turn up again next week with a similar confidence and attitude.

"But we'll enjoy tonight, and all the hard work that’s gone into getting us here, then decompress tomorrow, and we go again for next week. I’m pretty excited about where this team can go because I think we’ve improved steadily every week."

Head coach Foster echoed his skipper's sentiments.

He said: "It was the patience we showed tactically. Sometimes when you get out early you can loosen up a lot but I thought in that second quarter we stuck to what was working.

"We saw space and we took it. There was some nice instinctiveness about it, too. We're building something here."
