His Crusaders teammate George Bridge is probably already in line for a call up as an outside back to cover for Rieko Ioane and Ben Smith (who is equally at home on the right wing) because right now it's difficult to see how an (albeit injured) Waisake Naholo can find his form of old with little sign of it in the first half of the Super Rugby season.
Jordie Barrett offers height and versatility too – and, like Ben Smith, he's another almost guaranteed a trip to Japan covering fullback/wing, but if the selectors want a fullback specialist at the top of his game they would struggle to go past the 24-year-old Havili.
"He's been in the [All Black] group in the past – he's bashing the door down to be noticed," said Crusaders backs coach Brad Mooar recently.
"I think he is leading the competition or is right up there in terms of defenders beaten and he's playing very strongly for us."
The thing about Havili is that he generally goes about his business with such efficiency and neatness that he can blend into the background – especially in a team such as the Crusaders who are near obsessed in their desire to do the basics well.
The Tasman player has pace but also a surprising power that can take him clear of defenders. He had one of his best games of the season against the Highlanders in Christchurch and most notable then was his ability to put his teammates into space by running straight and passing at precisely the right time.
With only five tests before the All Blacks first game of the World Cup against South Africa in Yokohama on September 21, there may not be enough time for outside back Braydon Ennor to prove himself, but the 21-year-old has admirers among the selectors for his rugby brain or ability to do the right thing at the right time.
He also has the ability to play in the midfield and, above all, pace. And on what should be hard grounds in Japan, the latter is something the All Blacks will need plenty of. They won't have McKenzie to help up the fatigue factor late in tests but in Havili, Bridge and possibly Ennor, they have other speedy options.
