A player of the match performance from Portia Woodman has helped the Black Ferns inflict a record final loss to Australia at the Canada Sevens.

The Black Ferns were sublime on both attack and defence as they routed Australia 46-0 at Westhills Stadium in Langford for their second straight World Series title and third consecutive major title - Commonwealth Games gold included.

Kaikohe's Woodman showcased her power and speed as she scored two of New Zealand's first-half tries, essentially ending the contest with a full half to play.

Niall Williams and Kelly Brazier also had doubles while Ruby Tui and captain Sarah Goss also crossed the line in one of the more dominant sevens performances in recent memory.

Woodman said keeping control of possession was always going to be a big factor going into the tournament.

"If you hold on to the ball you're going to score more tries, so that was our biggest theme going into this final," she said.

Woodman continued to show why she leads both the try- and point-scoring tallies as she crossed for her 36th of the series during the final, bringing her points total up to 180.

She is seven tries ahead of fellow Kiwi Michaela Blyde on the try ladder and is 31 points ahead of American Alev Kelter.

While the win was a fantastic effort, it may not be enough to help the Black Ferns win the overall title because Australia still hold on to a four-point lead.

Australia have not finished worse than third during the World Series while the Black Ferns had to overcome a slow start after finishing fifth in the opening leg in Dubai.

Captain Goss said she was happy all their efforts had paid off in Canada.

"I'm really proud of the girls," she said.

"We've put in a lot of effort and been on the road for a long time. We're really stoked with the result, and happy to be heading home for some recovery."

Earlier in the tournament hosts Canada found out just how tough Woodman is to stop in full flight as her hat-trick of tries was the difference in the Black Ferns' 17-12 win before they overcame a stuttering start against the USA to run away with the 33-10 semifinal victory.

The Black Ferns now have a few weeks to prepare for the final leg of the World Series in Paris from June 8-10.

They will have to finish at least three spots higher than their Australian counterparts to secure overall honours.

If they finish two places ahead in Paris the series will go to a tie-breaker.

Should teams finish equal on series points at the conclusion of the season, overall scoring differential in the season will decide the winner. If that is all square it goes to total try count.

If both teams still cannot be split, the crown will be shared.
