Since that test Savea scored a try in each of his next three tests against Australia in Wellington, Argentina in Hamilton and South Africa in Christchurch. He now has an extraordinary 43 tries in 48 tests.
As a finisher Savea is virtually without peer, but it is his reliability which really sets him apart now. He struggled under the high ball at times in his first year at this level but is now a safe pair of hands; his ability to tidy up at the back alongside Ben Smith and Israel Dagg makes the All Blacks a formidable defensive unit.
But although Hansen has named an extremely strong line-up as he and the All Blacks chase a record 18th consecutive test win, eyebrows from outside the group might be raised at the selection of Matt Todd in the No7 jersey ahead of Ardie Savea.
Todd made his starting debut on the openside flank against the Boks at Kings Park and clearly did enough to convince Hansen to leave him there. It is an intriguing selection given Savea's form since his debut during the Wales series and has clearly been made to combat the threat of the returning David Pocock at the breakdown.
It is a big show of faith, too, in Todd, who has had to show immense patience during the reign of Richie McCaw and then watched as first Sam Cane and then Savea overtook him.
The 28-year-old, preparing to play in his sixth test, doesn't have the power of Savea, but is an extremely good defender and is quick to latch on to the ball on the ground - crucial attributes for combating Pocock. Savea will be relied upon to drive the pace to a level the Wallabies can't withstand in the second half.
The impressive Anton Lienert-Brown retains his place at centre alongside Ryan Crotty, with Aaron Cruden forcing his way on to the reserves bench after recovering from a groin injury, with Malakai Fekitoa also named on the bench.
"Australia will be coming here with a lot more confidence than when we played earlier in the season. They've made some significant changes to their game and would like nothing better [than] to end their Southern Hemisphere test season with a win," Hansen said.
