Organisers of the annual Kiama Sevens rugby tournament will continue to work with the ARU and IRB to improve the time-honoured competition and keep it as relevant as possible to Australian clubs.

The 42nd carnival went off without a hitch on Saturday under its new round-robin format.

Tournament co-ordinator Mark Bryant had travelled to Hong Kong last year to meet with ARU boss Bill Pulver and former Wallabies player Michael Hawker.

The aim was to adapt the Sevens format to align it more closely with IRB laws and allow the top-class players more time on the park as they fight for selection in the national teams to contest the 2016 Olympics.

The ARU even sent its own referees to officiate this year's tournament.

Bryant is keen to tinker with the specifics of the carnival further over the coming 12 months.

"It was the first time we've followed this model," Bryant said.

"It's all about creating a pathway to get to the Olympics so we tried to stick as closely as we could to the IRB laws and what works for the ARU. We ran on time which was really good, we could probably tighten it up a bit, but we want to talk to the referees to see what they think.

"We'll also talk to the coaches and managers and say what are your thoughts on any changes.

"As a comp we want to work with the teams."

A total of 40 individual teams descended on Kiama Showground on Saturday to fight for a share of the $25,000 purse.

It was Sydney's Manly A which took home the lion's share of $10,000 by beating Warringah 7-5 in the main draw final. It was a fierce and physical affair as defence stole the show from the usual attacking flair of the seven-a-side game.

"You normally see fatigue creep in by game five but these guys were tackling each other, hitting each other hard," Bryant said.

"They absolutely hate each other too, they were belting each other left right and centre."

The Manly club missed out on two trophies when Manly B lost the Plate final 29-7 to East Sydney. Warringah won the women's Vase 10-7 over Penrith RSL, and Muswellbrook flogged host club Kiama 40-0 in the Country Cup final.
