New Zealand have made two changes for their showdown with Argentina in the Rugby Championship at the weekend.
Veteran Andrew Hore takes over from Dane Coles as hooker, adding experience to a forward pack expected to be pushed hard by the Pumas.
The 35-year-old, capped 79 times for New Zealand, returns after being rested for the home victory over South Africa.
The injury-forced replacement of star fly-half Dan Carter with Aaron Cruden was the only other change from the starting 15 that defeated South Africa 29-15 in Auckland earlier this month.
Ma'a Nonu and Conrad Smith will play their 50th Test together in the centres in La Plata on Saturday, equalling the world record for a midfield partnership currently held by Ireland's Brian O'Driscoll and Gordon D'Arcy.
New Zealand have posted 16 wins and one draw in their 17 meetings with Argentina but Hansen said they would not underestimate a team desperate to score a historic first win in the Rugby Championship.
"We are very happy with where Dane is at and with his performances of late," said All Blacks coach Steve Hansen.
"But like a lot of the young players, we are also mindful of managing their game time as part of their development so have brought in Andrew to start this week." Source : http://www1.skysports.com/rugby-union/news/12321/8942384/rugby-championship-new-zealand-change-two-for-pumas
