Wallabies Coach Ewen Mckenzie remains optimistic despite suffering a 47-29 setback against the All Blacks in their opening game of the 2013 Bledisloe Cup. However, there is an air uncertainty if the game could be played at the Westpac Stadium in Wellington because of the magnitude 6.6 earthquake that struck the place on Friday.

Matt Toomua, Scott Sio, Scott Fardy, Tevita Kuridrani and Nic White, all played for the first time for the National Team and experience, more than anything else, could only do them good.

Holding onto the ball is one of the major key points that Mckenzie is going to emphasise on, in preparation for the upcoming match.

"Every time you lose a game it is disappointing," Mckenzie told rugby.com.au.

"We were level pegging there for some time in the game, but you have to respect possession."

"We had possession there at times where we did some good things. We made a bunch of line breaks but we didn't treasure the ball enough."

"They were very good on counter attack. We knew that before the game. They score a lot of their points from turnovers and it was one of the things we did discuss - controlling the ball, and not giving them loose to play with." He stressed.

"We didn't control the ball and they were able to do some of the things they are good at. And you pay a price for that."

The Wallabies mentor believes that they will be able to make the proper adjustments coming into Saturday's encounter.

"In among it there were some pieces that we did like, and there are areas we can certainly improve ... no question about that" he continued.

"But we got some good width in our game and some of the interplay we worked on wasn't bad.

"The lineout was good. The scrum was a bit of a lottery for both teams. It was a bit of mixed bag there."

The Wallabies are still set-out fly on Wednesday for Wellington in spite of the earthquake incident, at this juncture.

''We'll obviously rely on the local authorities to guide us but we're getting no information that we're not going to be playing there at the Cake Tin and having a crack." Mckenzie told the Sydney Morning Herald.

''We'll just go there and prepare as we've already planned to do.''

On the other hand, the Westpac Stadium will be inspected by the authorities to ensure the safety of the players and spectators alike.
