For the first six weeks of Super Rugby, it looked like the penny hadn't dropped. Ioane began the season on the bench for the Blues and did little in what time he was offered on the field, to change his situation.
His lucky break came when Jerome Kaino had to have knee surgery. Ioane was elevated to the starting team and told to make his presence felt.
Suddenly, there were signs he was getting it. He didn't drift out of the contest the way he previously had.
He manned his post at all times - got his shoulder square in the contact zones, dropped his body height and made more telling tackles.
He even turned up at breakdowns without his clipboard, forfeiting his previously self-appointed role as a ruck inspector where he would seemingly do nothing more than pop his head in for a look, check everything was it should be and then tootle off.
He's still got a way to go but the fact he has obviously taken on board the need to fix obvious failings in his game and preparation, have been enough to earn him an All Blacks call-up.
And again, his lucky break has come from Kaino's injured knee. The veteran loose forward will fly home on the weekend and Ioane will join the squad once he has played for the New Zealand Maori against the French Barbarians in Bordeaux on Friday night.
He'll scoot across to Lyon by train and most probably, despite the short turnaround, be in action for the All Blacks on Tuesday night.
With Kaino due to fly home on the weekend due to his injured knee, Kieran Read and Sam Cane certain to be rested and Liam Squire recovering from a virus and expected to play against Scotland at Murrayfield on November 18, the All Blacks are going to be short of loose forward options in Lyon.
Luke Whitelock will most likely start at No 8 in Lyon with Ardie Savea at openside. But blindside will come down to a choice of Matt Todd playing out of position, or Vaea Fifita or Ioane backing up from the weekend.
Ioane, if he doesn't start, is probably going to be on the bench and from there he will have the opportunity to deliver further evidence of his new found self.
He has the ability to be a superstar. He wouldn't finish so far behind Fifita in a foot race and at 115kg, he's almost impossible to take down at full flight.
He has the ball skills of a midfielder and the instincts of a wing and if he can continue to do what he was doing with the Blues in the back half of the Super Rugby campaign, it wouldn't be a surprise if Ioane wins a test jersey before the end of the tour.
If he does, it will cap an incredible, crazy 12 months.
