"I don't feel like I need the games to get back up to that level. It's been really good, I've been able to do a lot of re-conditioning, a lot of running and weights and they are probably the things I haven't been able to do lately. My fitness is fine and it's just a matter of getting up to test match level.''
Read has proven he is able to slot back into test mode on a diet of limited match time - such as the World Cup where he was a late starter due to an ankle injury.
He is like fellow loose forward Richie McCaw in that respect, and the Crusaders pair will form a relatively new trio with Liam Messam after the Chiefs player was picked ahead of Adam Thomson and Victor Vito.
Messam has been rewarded for his recent good form and his last outing for the All Blacks, when he impressed at blindside flanker in the big win over Ireland in Hamilton.
Coach Hansen said Messam had matured and was becoming more consistent. The No6 jersey was among the most hotly contested for this first test of the Rugby Championship.
The others were left wing, with Hosea Gear getting the nod over Julian Savea, and lock, Luke Romano beating fellow newcomer Brodie Retallick as Sam Whitelock's partner.
"I think Liam will slot in really well,'' Read said. "It's just a matter of doing what he's been doing all year - playing really aggressively and really just adding to the jersey and the team.''
For his part, Messam said the Chiefs' winning run, environment and coaches were the biggest factors in his improvement.
"I've probably got more of an edge to my game this year. I've been working hard and put in a lot of effort during the season ... I always get that `too small' or `not big enough' tag but I just try to fly in and try to hurt people.''
Hansen said Romano's bulk and ball-carrying ability got him the nod over Retallick. He said: "I think locking now is a combination. The big ball runner versus the two streaky, skinny guys, even though they're not that skinny, that combination worked better for us in the Irish series and we want to have another look at it.''
That's good news for Romano, a 26-year-old late developer who made his international debut in the third test against Ireland. It's now up to him and Messam to cement their spots in the pack as the All Blacks seek to defend the Bledisloe Cup which they have held since 2003.
