CENTRE Scott Williams says everything will have to be "on the money" if Wales are to upset the odds against world champions New Zealand.

Warren Gatland's men face three daunting Tests against the All Blacks in Auckland, Wellington and Dunedin while they also tackle the in-form Chiefs in a midweek clash.

They headed Down Under on the back of a deflating 27-13 loss to England at Twickenham where the margin of defeat would have been even greater had home fly-half George Ford not endured a nightmare from the kicking tee.

Wales have not beaten New Zealand since 1953, losing 26 successive Tests, while their away record in the fixture shows seven defeats from seven starts, conceding an average 40 points per game.

Everything points towards a chastening tour but Scarlets midfield man Williams, who made his international return at Twickenham following a serious knee injury sustained on the same ground during last autumn's World Cup, says they must remain upbeat.

"There is no point in us going to New Zealand with negative thoughts, otherwise it's going to be a long couple of weeks," he said. "We've got to take the positives and a couple of work-ons into the next two weeks.

"I think everyone is going to have to play one of their best games to be able to beat New Zealand. That's what it is going to take, and that's what we have been training for in the last couple of weeks.

"It's trying to lift the standards up. Every pass, everything you do is on the money, because when we play New Zealand, it's going to have to be."

Williams is one of four specialist centres in the squad with Jamie Robert and Newport Gwent Dragons prospect Tyler Morgan soon to be joined by Jonathan Davies, who missed the Twickenham encounter because of Top 14 commitments with Clermont Auvergne.

Davies is likely to wear 13 on his back in Auckland with Williams likely to have to settle for a spot on the bench.

The 25-year-old hopes to reap the rewards of his London run-out after looking understandably sluggish due to a hamstring strain depriving him of game time in the Guinness Pro12 run-in.

He said: "It felt like my first game back, but it was a good blow-out. It always takes one or two games at international level to get used to the intensity, so hopefully, I will be better next time around."
