Asked what it took to make such gains, Taylor said: "You're surrounded by the coaches and one of the world's best trainers, so that always helps. And then you've got the nutritionist who is always on your case, giving you the old fat pinch, which is good.
"Obviously it takes a lot of weights, a lot of eating and a lot of top ups to keep my fitness up.
"I'm 112kg now. My goal was 110kg so I've surpassed that a little bit. On a good day in Super Rugby I was 108kg. Four kilos doesn't sound like much but you definitely feel it."
The extra size and strength allows Taylor to make more of an impact in the scrum and in the contact areas, although he joked that he felt it "mainly in my lungs and in my legs, trying to get around the paddock".
The 25-year-old has impressed with his composure, pace and skill level since his debut last year, a match in which he scored a try on his home pitch. He has made only two starts during his test career - against Namibia in the World Cup, and Australia in Sydney in August - but is knocking on the door of another one as he becomes increasingly comfortable in the All Blacks' set-up.
"It's a younger environment this year," he said. "Last year I was probably a little bit more tense... but this year I feel more confident in the group and ready to play some good footy."
