All Blacks

RNZ reports Kaino will rejoin the All Blacks squad for the final Test of the Rugby Championship against South Africa a week later.

Fellow loose forward Sam Cane and first five Aaron Cruden have been ruled out for the rest of the Rugby Championship due to injury.

Matt Todd and Damien McKenzie will travel as injury replacements for Cane and Cruden while George Moala and Waisake Naholo return from injury.

The All Blacks won the Rugby Championship with two rounds to spare after beating the Boks 41-13 in Christchurch while the Wallabies halted Argentina in Perth later in the day.

Fox Sports reports New Zealand players are centrally contracted to the national side, with the NZRU having the ultimate say in player conditioning and welfare, and the 92-Test international believes it is allowing the All Blacks to create a gulf between them and the rest of world rugby.

After taking an early lead through Bryan Habana in Christchurch, the Springboks handed back the initiative immediately, Elton Jantjies dropping the kick-off which led to Israel Dagg's try.

The All Blacks never looked back from there, running in five more tries in a resounding 41-13 triumph, with their Rugby Championship title confirmed following Australia's 36-20 win over Argentina in Perth.

After five impressive bench appearances, dynamic flanker Ardie Savea is in the run-on side to face South Africa in Christchurch on Saturday, replacing the injured Sam Cane.

It is the only starting change from the side who roared away late to a 57-22 win over Argentina in Hamilton last week, extending the unbeaten All Blacks' lead in the Rugby Championship.

Openside flanker Cane suffered a hamstring injury which will sideline him for at least a month, opening the door for 22-year-old Savea to show his prowess from the opening whistle.

The All Blacks are three wins from three heading into Saturday's match, while South Africa have won just once against Argentina, before losing to the Pumas and a struggling Australia side.

But Kaino said Argentina had put enough pressure on New Zealand in last weekend's test in Hamilton to encourage any side, let alone one with the pedigree of the Springboks.

The Pumas put the world champions under significant pressure for more than 50 minutes in Hamilton on Saturday, claiming the lead on three occasions.

However, a one-sided final half-hour saw the All Blacks run in 33 points without reply to secure an ultimately emphatic victory.

"Just an ideal game for us, wasn't it," said Hansen. "We've come off two pretty successful weeks against Australia and then [we were] put under a lot of pressure in the first half and had to find some answers.

Crotty scored New Zealand's opening try of the Championship in the first of two victories over Australia, as Steve Hansen's men retained the Bledisloe Cup.

The Crusaders centre missed the second clash through injury, with Anton Lienert-Brown coming in to make his debut.

However, Crotty is now fully recovered from his head knock and will don the number 12 shirt once again in Hamilton on Saturday.

"In selecting this team, we felt there was the need for consistency," Hansen said. 

 A listening device was discovered in the team's hotel ahead of last month's Bledisloe Cup in Sydney and the police in New South Wales are reportedly not ruling out the possibility someone in the New Zealand camp planted the device.

A police source has told the Sydney Morning Herald if it turned out to be someone within the New Zealand camp, they would "absolutely" look at criminally pursuing the matter.

Tew says he's waiting for the police to complete their investigation.

RNZ reports the All Blacks have begun the series with two straightforward wins over Australia, the second in Wellington becoming a niggly affair when the Wallabies tried to provoke the All Blacks in retaliating.

Lock Brodie Rettallick says he doesn't mind that style of game as it indicates the opposition isn't focusing on the game although he admits it can get frustrating.

"There's a line where you have got to stand up as a team and not just stand there are take it and there's also a point where it diverts you from what you are doing.

RNZ reports first-five Beauden Barrett also showcased his growing stature as the starting No.10 with nine points from the boot and his all-round play drove his side around the field in a match that failed to reach the same heights as last week's opener.

Wallabies first-five Bernard Foley slotted two penalties, while debutant Reece Hodge landed a monster penalty in the first half for the visitors, who rarely threatened on attack and lost their sixth successive match.
