Then came the last-minute thriller against the Blues when Conrad Smith capitalised on a break by Beauden Barrett to score with 15 seconds remaining. Barrett then coolly slotted the conversion for the win.
Captain Smith has been a standout at the Hurricanes in a season when few senior All Blacks have made much of a mark, and Hammett reserves special praise for him. But first comes that work ethic, for which the coach has a simple explanation.
"It's where we've started," he said. "If there's no obvious starting point in terms of your strengths, the best place to start is hard work and that work ethic side of things, and we all know that one of the best places to work on that is your defence because you can't do that on your own.
"There's a reason why we won those games. It's around that work ethic and never giving up; hopefully what people are seeing is a pattern and ability to play different styles.
"That's getting us wins and that's great, but what's probably good about close results is we review really honestly and that we keep getting the gains and whether we win or lose I expect our players to be better rugby players by the end of the week."
As for Smith, he's a rock in the middle of a backline showing immense potential in halfback T.J. Perenara, first-five Barrett and Andre Taylor, who's proving a revelation after his move from wing to fullback.
"He's been absolutely outstanding," Hammett said of Smith. "One of the reasons I selected him as a captain is because he's a leader 100 per cent of the time. He gets the balance really well and what I like about him is he can be social, he can be the guy who dresses up when we have dress-up parties and get comfortable in that and can have a beer during the week in a social situation.
"He can speak to a bunch of corporates but he gets the balance. And the other thing is he doesn't expect someone to do something he won't do."
Hammett appears to be bringing the best out of the younger players in his squad and it would be easy for him to bask in the fact he has put one over his many critics. That's not really Hammett, who possesses a well-rehearsed phrase about vindication.
"I think vindication is served best for people who are vindictive so, for me, not really," he said. "I'm not a guy that holds grudges. I'm pretty focused on what I want to achieve and on this group."
