The All Blacks won't use pedantic refereeing as an excuse for a patchy Bledisloe Cup performance and will look within for a better second Test display in Auckland.
Like the Wallabies, the All Blacks have been self-critical, even though they won the Sydney opener 27-19.
Errors and the non-stop whistle of Irish referee Alain Rolland made for a poor spectacle and both teams have vowed to improve at Eden Park.
Hansen said his side didn't adapt well enough to Rolland's officious approach in handing out 28 penalties for the match, many for technical faults.
"Referees are what they are and you've always got question marks about how they're going to interpret things," Hansen told journalists.
"I think the referee may have made a couple of mistakes himself but we certainly contributed to him blowing the whistle.
"It's no use us sitting here and whingeing about the refs. You can't play without them, so just enjoy them."
An unchanged team seems likely this week although prop Tony Woodcock would have his sore ribs assessed at training on Tuesday.
Hansen wanted the same players to remedy the mistakes that dogged them Sydney.
One that stood out was an inability to deliver clean lineout ball to halfback Aaron Smith. Just six of New Zealand's 14 lineout throws went to plan, Hansen said, prompting the need for some "relationship meetings" this week.
"When there's something in your performance that you're not completely happy with, that makes you dig a bit deeper than you would if it was a super performance.
"One of the challenges we've set ourselves this year is not just looking at the opponent. It's dealing with yourself and seeing if you can be better than the last time you played."
Hansen predicted he'd use his bench this weekend as he anticipated the ball would be in play more. A stop-start Test in Sydney meant fatigue wasn't a factor.
