Rugby World Cup: Black Ferns still seeking perfect performance as campaign continues against Wales

The Black Ferns are demanding a more complete performance as they look to prove their World Cup credentials in their second pool match on Sunday.

With Wales ranked seven places below them, the Black Ferns should be largely untroubled, but concede they can't let poor habits creep into their game.

After overcoming a 17-point deficit in their World Cup opener last week, Demant doesn't want to see slow starts become routine, knowing the calibre of teams they're likely to face later in the tournament.

"It's [about] making sure we start the game how we want to start it, and playing our game instead of waiting," she said.

"Further down the track, we can't allow teams to punish us like that."

The Black Ferns should get little in the way of resistance from Wales, a team they've never lost to, and Demant says everyone is responsible for ensuring that doesn't change.

"Everyone has their own individual accountability to do their job, do their role," she added.

Director of rugby Wayne Smith is eager to give all squad members the chance to do that.

He's acutely aware of just how much has been sacrificed for this group to be able to pull on the fern at home.

"They've committed a lot to be here," he said. "We've got a couple with children, we've got people leaving jobs to be here.

"It feels important to give them a crack."

And Smith is urging them not to be overawed by the occasion. It's been a big focus for the Black Ferns following their sluggish start against Australia, and Smith is sure this group has the resolve to avoid a repeat tomorrow.

"It's a really intelligent group, who care deeply about what they're doing," Smith added. "So you've got the attitude to do it, now it's a matter of bringing it out."
