The south Auckland gym where Joseph Parker cut his teeth in boxing, is also a place where New Zealand's world champion heavyweight champion is also inspiring the next generation.
There's a certain symmetry to the fact the biggest opportunity of Mose Auimatagi Junior's career will come when he fights on the undercard of Joseph Parker's title unification bout against British superstar Anthony Joshua in Cardiff on Easter Sunday.
Now 22 and the New Zealand champion in the middleweight division, Auimatagi Junior was just 14 when he walked in the door at the Papatoetoe Boxing Club.
By then Parker was a Youth Olympic Games silver medallist, and all the attention he was getting served as motivation for a younger boy from the same neck of the woods.
"It had a big impact on me," Auimatagi Junior said as around 15 of his club-mates diligently skipped, shadow-boxed and strained their way through sit-ups behind him.
"When I started training here, Joseph was still coming up and he was the one getting interviews. I was one of these skippers, watching, getting motivated and I'm getting interviews now.
"One of these guys skipping behind me, they're going to get [that] too.
A founder of and the driving force at the club, Grant Arkell was Parker's amateur coach for almost a decade and he says Auimatagi Junior is far from the only one who has been inspired by Parker and others who have pounded the pads at his gym.
"A lot of little kids want to be Joseph Parker, just like when David was fighting, everybody want to be David Tua.
"We used to have David Tua come in here and train and they'd all trail him around the gym.
"It's a big inspiration for young ones who want to box."
Not that Arkell always expected that Parker would have that affect on others.
In fact, he remembers well the day a 10-year-old Parker appeared at the gym, and the first few years of what has since become a hugely successful career.
"[He was] a little short overweight boy, I won't call him fat, he's too big now.
"A little short plumpy boy who wasn't really interested, he had more fun running round talking to the others.
"Joseph was more interested in fishing, he quite often went 'sick'."
Arkell goes on, explaining how Parker failed to even turn up for several fights in those early years and describing him as a mediocre boxer.
But that didn't mean the distractible teenager's coach hadn't noticed the speed, quickly increasing size and, above all, intelligence.
After urging him not to let his natural talents go to waste, Arkell said Parker finally begun to start realising some of his potential.
"He was fighting well out of his class as an amateur.
"He was fighting men when he was 15 and 16, because I couldn't get anyone [his own age] to fight him.
"He fought a boy 20 kilos heavier than him once, destroyed him in two rounds."
While his fighter was on an upward curve, Arkell believes the true turning point did not come until an 18-year-old Parker collected silver at the 2010 Youth Olympics.
It had not been an easy road getting to Singapore, but Arkell said the battles inside, and outside, the gym proved well worth it.
"There was a trust in Mangere that runs the swap meet on a Sunday, they came to the fore and got him and I to Singapore, I think it was about six-and-half, seven thousand dollars to get there.
"From there on we did fundraising, selling chocolates and bits and pieces, to get him further a field because Boxing New Zealand didn't have a lot of money.
"Every tournament he went to he just got better and better."
Despite his improved dedication, Parker ultimately came up short in his quest to attend the 2012 Olympics in London and soon announced he was going professional.
Although he strongly disagreed with that decision, Arkell is happy to admit he has been proven wrong and says the two remain on great terms, with Parker often dropping by the gym when he is back in New Zealand.
"He comes in here and sometimes trains with boys, signs posters and things like that.
"He tells them to train [hard] and listen to me, which he didn't do."
These days, though, the Papatoetoe Boxing club has a new rising star, and Arkell is adamant Auimatagi Junior can be as good as Parker if he gets a similar level of support.
Victory against his unbeaten opponent in Cardiff would be the perfect way to show he deserves that, something Auimatagi Junior is acutely aware of.
"I mean this is probably the biggest opportunity any New Zealand fighter has had besides Joseph and I'm just blessed to get it.
"This is make it or break it, this can open many doors for us if things go right.
"If we do well, the world's our oyster."
With proof of Parker's success set to be everywhere Auimatagi Junior looks, you can be sure inspiration won't be an issue.
