NSW backrower Dean Mumm has no concerns about the Waratahs' poor record at Eden Park and is looking forward to his homecoming of sorts in Auckland for Friday night's Super Rugby finals clash with the Blues.

The Waratahs lost 31-17 to the Blues earlier this year at Eden Park and have won just once at the ground - in 2009 - in more than 80 years.

"We don't have a super record at Eden Park, but I suppose the good thing is that the win that we've had was in recent times," Mumm said.

"A number of the guys that played in that game ... that win over there ... are still playing now. I don't think it's so much of a hoodoo as it's been made out to be.

"I was born in Auckland but I haven't spent too much time there since then. It's always nice to go back but all my family is a bit further south, so it's not too much of a home."

The Waratahs, who clinched their finals spot with a record 41-7 triumph over the Brumbies in Sydney on Saturday night, have lost all four of their overseas games this season - to the Crusaders, Blues, Bulls and Sharks.

But Mumm said it is more important for the Waratahs to concentrate on how they play and not where they are playing.

"We're certainly confident of our ability to go there and play well and I think that's what our focus needs to be on," Mumm said.

The Waratahs have again been forced to reshuffle their line-up because of injuries.

First choice hooker Tatafu Polota-Nau (knee), prop Al Baxter (head knock) and five-eighth Daniel Halangahu (hamstring) were all ruled out of the Eden Park encounter.

With Halangahu and Berrick Barnes unavailable, Kurtley Beale is set to switch from fullback to five-eighth, while Lachie Turner is the front-runner for the fullback spot.

And with back-up hooker Damien Fitzpatrick also injured, John Ulugia will start with the uncapped Elvis Taione promoted from club rugby to the bench.

"We've had a number of changes every week throughout the year and having a different line-up from the previous week is nothing different for us," Mumm said.

In a boost for the Waratahs, coach Chris Hickey said Wallabies centre Rob Horne is a chance of making a comeback after a long layoff with injury.

"He's just not quite ready at the moment but, if we make the final in a couple of weeks, I wouldn't rule him out of making a return," Hickey said.
