Dan Carter and Sonny Bill Williams have been left out of the 31-man All Blacks squad for the match against the Springboks at Ellis Park on 25 July.
Highlanders flyhalf Lima Sopoaga has been preferred as the third No 10 behind Beauden Barrett and Colin Slade.
'Normally if we had a squad of 31, both of them [Carter and Williams] would be in it and would be coming,' Hansen said. 'Sonny has got bit of a busy schedule so we will let him have some time at home and DC can have some time at home as well, along with the other guys.'
