Aaron Jarvis has been called up to the Wales squad for the tour of New Zealand due to injury concerns over prop Paul James.

Ospreys' tighthead prop Jarvis has been drafted in by Warren Gatland as James is not expected to be fit for the first Test against the All Blacks at Eden Park on Saturday or the clash with Chiefs next Tuesday.

The Clermont Auvergne-bound Jarvis trained with Wales for a fortnight before they headed out to New Zealand and could win his 18th cap this weekend.

Wales assistant coach Shaun Edwards said: "You always want a fully fit squad and Paul has been grafting hard to be fully fit particularly for the game on Tuesday.

"Unfortunately it doesn't look as though that is going to happen and we have brought Aaron out as cover."

New Zealand have won 26 games in a row against Wales, an incredible run that stretches way back to 1953.

Assistant coach Rob Howley said Wales are looking to adopt a siege mentality in the three-match series against the world champions.

"We are here to try to change history from what has gone before us. That's our goal," he said. "When you talk about confidence and self-belief, there is an external perception about where this Welsh team is and an internal one.

"For us it is about turning the belief and confidence we have and our own internal perception into a bit of a siege mentality.

"That can often benefit teams when you come over to the southern hemisphere because history is against you. We need to change history and by trying to create a siege mentality it will hopefully put us in a good space some time on Saturday and help us to put the All Blacks under pressure on some occasions.

"We are all aware of the fact it is New Zealand's first game since the World Cup, while we have had several games. Everyone talks about them losing Conrad Smith, Ma'a Nonu, Dan Carter and Richie McCaw, but I've never know a transition period in New Zealand rugby.

"I only played against them once, but every All Blacks team I have coached against has been a pretty strong side. They have strength in depth and that is something we admire from afar.

"But there is an opportunity for us. They have a new captain [Kieran Read] and that often changes the dynamics of the group. When you play against New Zealand you will take every single per cent that might give you an edge. It is a huge, huge challenge, as we all know, but we are looking forward to it."
