The Black Ferns Sevens are entering the upcoming World Cup with the mantra, 'if it ain't broken, don't fix it'.
Speedster Stacey Waaka said the team won't change much for the tournament in San Francisco later this month, having won the last four events heading into the competition, including the Commonwealth Games.
"We've won the last four tournaments so we don't need to change much, I don't think," she said.
"We know that other teams are going to come out with things unexpected so we've kind of prepared for that but whatever happens on the day, we'll be ready."

The squad for the tournament was unveiled today, with an experienced 12-strong team selected to defend the title they won five years ago in Moscow.
Waaka said the environment in the team before the squad was named was something special.
"[There was] such a good buzz," she said.
"There's 20 of us and we're all vying for spots so everyone knows they've got to put in the hard work.
"I felt sorry for the coaches picking the team - but really, really stoked I'm in!"
Black Ferns Sevens team: Shakira Baker, Michaela Blyde, Kelly Brazier, Gayle Broughton, Theresa Fitzpatrick, Sarah Goss (captain), Tyla Nathan-Wong, Ruby Tui, Stacey Waaka, Niall Williams, Tenika Willison, Portia Woodman.
