Although Sonny Bill Williams was down on the team list to play for the Baa Baaz, the All Blacks midfielder was a no-show, however several members of the public said they had seen the rugby star around Whakatane.
More than 70 teams took part in the two-day event, with teams from Australia adding an international flavour to the tournament.
Competing in the men's restricted division, Marshall lit up the field with his blistering speed, sleight of hand and trademark sidestep.
Marshall said he enjoyed coming back to his home town and taking part in a tournament he used to play in before he made his name as a league star.
"It's always great to get back home," he said. "I don't get back that often, so it's a good time to catch up with family and have some fun playing touch."
The Kiwis captain said it was also good to play alongside players like Weepu.
"I had to teach him a few moves - it's just the way it is," he joked. "It looks like he's been eating heaps since the World Cup and was a bit down on pace today."
Although Weepu was carrying a few extra kilos, it didn't stop the World Cup winner from showing off his speed around the field and skills, firing long bullet passes to open up space for his teammates.
Weepu, who has attended the tournament for the last couple of years, said he used the event to have fun as well as to get in some pre-season training.
"I've already been doing some pre-season stuff but this is a way to have some fun and get some fitness," he said.
Although the Baa Baaz won their pool, they qualified only for the plate final which they lost to an Auckland side 4-3.
The open men's final was won by Liam Messam's Waikato side Lock who beat Auckland Bullets 5-1.
