New Zealand captain Richie McCaw has warned his team against complacency ahead of the Bledisloe Cup clash with Australia, with the All Blacks seeking to wrap up the Tri Nations title at Christchurch's AMI Stadium on Saturday.

McCaw insists last week's 49-28 win over Australia in Melbourne was not as comfortable as it appeared, particularly at the breakdown.

'We've got to make sure we are better there,' said McCaw.

'And I'm sure they will look at areas where they can be better too.'

McCaw noted his opposing skipper Rocky Elsom's view that there were too many New Zealand bodies lying around when his side wanted quick ball.

But McCaw said New Zealand had the same opinion and added that conceding turnovers was a frustration that every team wanted to eliminate.

'I think the big thing for us is that we want to focus on our performance rather than totally worrying about what they are doing,' said McCaw.

'It's our last home Test and we want to put a good performance here before we get on the road again and that's a big motivating factor.

'They're going to fire into it - they always do - and we are going to have to match that.'

Elsom called for the Australia pack to ensure quick ball if they were to have any chance of ending their eight-game losing run against their trans-Tasman rivals.

He said: 'You've got to move those bodies as best you can whether they're on our side or attacking the ball. We've got to make sure that space is clear for Willie (Genia) to get out and do what he does best.

'We've got to be able to play our ball and play it efficiently. We've really focused on what we're doing and what we do when we have the ball.

'We showed at the back end of the game last week that we needed to hold on to it, look after it, and be a bit more careful at times.'

Scrum-half Genia is adamant Australia are capable of victory, even though the Wallabies have not triumphed in New Zealand since Dunedin in 2001 and have not won in Christchurch since 1998.

'Believing is the first part of winning,' said Genia.

'If you don't believe in it I don't think you should turn up, to be honest.'
