The 24-year-old Rees twice finished sixth on the famous Cemetery Circuit street circuit at this traditional post-Christmas race meeting, earning himself a podium position for the series, a competition that his father had won the previous season.
While his dad, Tony, and his younger brother, Damon, were both sidelined with injury, Mitch Rees ensured there was still plenty for the Rees camp to smile about.
"It's disappointing for me, naturally, that I could not defend my Suzuki Series crown and that I'll also be unable to defend my national superbike championship, but that's what happens in racing sometimes," said Tony Rees.
"It was the year 2000 that I last broke a bone in racing. I got cleaned out in the first corner in one of the races (at the Suzuki Series opener) in Taupo and then I crashed ... my own fault really ... and had my hand run over by another rider (at round two) at Manfeild. With two DNFs in a six-race series, I didn't stand a chance of winning it again.
"But I have a replacement now don't I? I'm very proud of what Mitch had achieved and he's come on very strong in a very short time.
"Last season was his first ever doing road-racing, so it's been a pretty steep learning curve, but he's come close to winning races a few times now. I'm pretty proud of him really.
"Mitch and Damon both learned a lot from racing in Australia this year and they've both really gelled with the new-model Honda."
Rees said he expects to be back in action in six to eight weeks, but, in the meantime, he has "lots still to organise" for Mitch and Damon to tackle the 2018 Australian Superbike Championships, opening at Phillips Island in February.
"I'm not sure at what extent Damon will be in terms of fitness by then, but he's raring to go.
"We shared a pretty remarkable season at the end of 2016 and start of 2017 ... father and sons competing together, with me winning the Suzuki Series and then the national superbike crown and Damon winning the 600cc Supersport title at the nationals.
"The boys are very focused and we have had great support from Honda New Zealand. There's been a lot of commitment shown by all parties."
The four-round 2018 New Zealand Superbike Championships opens at Mike Pero Motorsport Park, Christchurch, on January 7, with rounds to follow at Timaru, Hampton Downs and Taupo.
