He and his teams avoided domestic defeat in their first four-year term and have lost just three times since - against France and against the Springboks at Carisbrook in 2008 and Hamilton a year later.
The All Blacks sit in Pool A at the World Cup where their rivals, in order, are Tonga, Japan, France then Canada. The only serious obstacle to the All Blacks qualifying top are France.
Les Bleus are talking about resting some of their leading players for their September 24 clash against the All Blacks at Eden Park.
"We have to play Japan and Canada and we need to involve the maximum of our players in those games," said France coach Marc Lievremont.
"After the Canada game we will decide what kind of team we will put out for the All Blacks, knowing that after that match we have to play Tonga which could be a final to decide who makes the quarter-finals."
Henry will want the All Blacks to face a French side of serious strength otherwise they will go into a quarter-final on a six-week diet of modest opponents since their loss to the Wallabies in Brisbane.
An insight into the French bunker on the North Shore might give him an answer but might not. Trying to find the French can be a mission as they were diverted from their planned training session yesterday.
Trying to nail down their thoughts is also like grabbing mercury as No 8 Imanol Harinordoquy underlined.
"It depends," he said about his side's approach to the All Blacks.
"If we win the first three matches you are sure to be in the quarter-finals. I think we have to play this match against New Zealand to win it but, if we don't, it will be a very hard challenge to beat Tonga and make the quarter-finals," he said.
Henry has spent this week re-evaluating his plans for the All Blacks' opening test on Friday against Tonga. At times his thoughts may have drifted 12km in a straight line from his lair across the Waitemata Harbour to the French headquarters.
At others he will have recalled the messy performance in Brisbane and the selection questions for Tonga and beyond as the All Blacks come into camp to start their seventh global tournament.
Henry and his selection cronies face a number of critical debates this week. Before Brisbane, the coach talked through his view that Dagg was a fullback and not a wing option.
That concept should get plenty of roundtable talk this week because it seems a waste not to have Dagg in the team. If Henry and his mates cannot bring themselves to cast aside Mils Muliaina from fullback, then Dagg has to be used on the wing.
Zac Guildford needs a rest so there is an immediate vacancy while Jimmy Cowan should win back the starting role at halfback.
Up front Victor Vito will get straight into work at No 8 because of the injuries to Kieran Read and Adam Thomson, and there will also be debate about starting Ali Williams at lock or using him from the bench.
The loose forward dramas probably mean Sam Whitelock will be used as backup so that should assist Williams' cause.
