WELLINGTON, Nov 25 AAP - The All Blacks extended their winning streak over Wales to 25 Tests with a flattering 33-10 win in Cardiff on Sunday (AEDT).

Three tries, all to forwards, inside the first 50 minutes pushed New Zealand 33-0 ahead before the injury-ravaged hosts dominated the last half hour to cross twice.

Both Welsh tries were unconverted while All Blacks five-eighth Aaron Cruden slotted seven from seven shots in an 18-point haul to blow out the scoreline.

It extends a winning streak over their traditional rivals to 59 years while stretching world champion New Zealand's current unbeaten run to 20 against all nations.

The result was no surprise, with the All Blacks having dealt comfortably with Scotland and Italy in earlier tour matches this month while Wales were coming off losses to Argentina and Samoa.

However, the late fight of the Welsh was impressive, having trailed 23-0 at halftime and lost three players to injury inside the first 20 minutes to add to their considerable injury woes.

Two tight forwards left the game after two minutes - prop Aaron Jarvis favouring his knee and lock Bradley Davies concussed after being struck by Andrew Hore with a swinging arm off the ball. That incident could result in a citing against the All Blacks hooker.

Wales inside centre Jamie Roberts was also an early casualty as New Zealand dominated the opening exchanges with fast, error-free rugby that had the hosts gasping at times.

Wales turned down two early kickable chances but the All Blacks weren't so generous as Cruden - called in to replace an injured Dan Carter late in the week - continually punished Welsh indiscipline.

Three penalties were followed by the conversion of a try to flanker Liam Messam, sparked 80m out by a counter-attack from fullback Israel Dagg.

Prop Tony Woodcock scored a try from a lineout that was eerily reminiscent of the lone try from last year's World Cup final against France.

Cruden's fourth penalty and a first Test try by lock Luke Romano in the 48th minute sealed the outcome before Wales mounted a stirring rearguard.

For Wales, replacement centre Scott Williams scored a remarkable try when driven over in a 14-man lineout drive before right winger Alex Cuthbert raced over with two minutes remaining.

The All Blacks will seek a tour clean sweep when they face England at Twickenham next weekend while Wales host Australia.
