One change appears on the bench with 76-times capped, and former British and Irish Lions, prop Gethin Jenkins (Cardiff Blues) completing his return from injury (calf) to be named in place of Ospreys front row Ryan Bevington.
"We were extremely disappointed to lose last week against the Springboks, but we did maintain momentum with aspects of the performance providing a host of positive points to take into next Sunday against Samoa," said head coach Warren Gatland.
"We have re-grouped and the players are looking forward to getting back out on the pitch to largely pick up where they left off last weekend. There are one or two areas we know we need to work on but we are looking for much of the same from all involved.
"We could not fault the effort, passion and commitment of the players last week and we have simply said we are looking for the same again against Samoa on Saturday."
Gatland will take his Wales side to his hometown of Hamilton for the first time during RWC 2011 when they line-up for their 'Captain's Run' at Waikato Stadium on Saturday afternoon.
And the Hamilton-born former Waikato captain and hooker, who made 140 playing appearances for his home province and also coached them to Air New Zealand Cup success in 2006, has called on the Waikato people to get behind his current charges against the popular Samoans.
"Samoa are going to have a lot of support, as will Fiji when we come back to play them in the final game of our pool, but we are hoping some of the Waikato people will be getting behind Wales as well.
"We played there on our summer tour of New Zealand last year and I told all of the players what to expect then and we all really enjoyed the experience and the welcome we had in Hamilton.
"It is a special atmosphere on matchday, it will be very much like coming home for me and we are hoping all the locals bring their Mooloo Bells and ring them for Wales!"
