The All Blacks will have a full quota of players available for selection, with Luke Romano and Tony Woodcock over the ailments that saw them miss the last test against Australia on August 25.
Taranaki pivot Beauden Barrett, who made his test debut against Ireland in June, will also spend time with the squad this week as he did before the test in Auckland recently.
New Zealand beat Argentina 33-10 at the quarter-final stage of last year's World Cup but the eventual winners were made to work, as Hansen said.
"I think they're coming here to try and win this game as they did in the quarter-final [at the World Cup]. They were bitterly disappointed at the end of that .... and they clearly thought they could win and we'll be expecting them to come out and try and win the game and we'll be doing our utmost to make sure we win."
Argentina opened the Rugby Championship with a 27-6 loss to South Africa in Cape Town but produced a much-improved display in front of their home crowd as they held the Springboks to a 16-16 draw in Mendoza last weekend.
The Pumas' last trip to Wellington saw them scrape past Scotland 13-12 in a group game at the World Cup last year, which proved vital in their run to the playoffs.
They boast a big, confrontational forward pack and Hansen said he wouldn't expect anything different from Argentina this week.
"Up front they're very, very strong and I think the backs are underestimated as well. So they've got talented counter-attackers and big strong backs so I think they're a good side and they proved that last week when they should've beaten South Africa. So we'll respect them and we'll go into this game the same as we would against any top nation and try and prepare as well as we possibly can."
