An intense eating and weights routine has resulted in back-up All Blacks hooker Codie Taylor packing on the power and size.
Taylor, who has played eight tests since making his debut against Argentina in Christchurch last year, weighed 108kg while playing for the Crusaders this season, but has put on four kilograms in order to make more of an impact at the higher level.
With Dane Coles undergoing a big workload with the Hurricanes going all the way in Super Rugby, a campaign which resulted in a painful rib injury, Taylor could be on the brink of a start in either Buenos Aires, where the All Blacks, who have already won the Rugby Championship, play the Pumas next Sunday, or against South Africa a week later in Durban.
All Blacks coach Steve Hansen has already indicated that he will look to mix things up in terms of his selections as he mitigates against high workloads and an intense travel schedule, and Taylor could be one of those provided with an opportunity.
"I have been focusing ever since that June series [against Wales] on packing on the size," Taylor told Radio Sport in Buenos Aires. "Test footy is a bit more physical and that's where I've got to - I've made a good weight to play test footy and now I just need the lungs to catch up."
