The Kiwi Ferns have been on form in their first three matches of the women's rugby league World Cup.

A fourth Women's Rugby League World Cup title beckons for the Kiwi Ferns and they look in the best form to do it.

The undefeated Kiwi Ferns will face England in Sunday's semifinal at Southern Cross Stadium in Sydney after they pummelled Papua New Guinea 38-0 on Wednesday night.

They have been convincing in their three pool matches, scoring nine tries in their 38-0 win over PNG, smashing the Cook Islands 76-0 and opening with a 50-4 win over Canada.

Kiwi Ferns 22-year-old vice-captain Georgia Hale says her side are determined to improve each match as no side is perfect and she is wary of a red-faced English side after being upset 22-16 by the Cook Islands.

"Yes it was a good win, but we are not happy to just win and we are always looking to do better.

"We have our moments, but there are areas we are looking at to improve. We need to have patience with the ball, hold possession, our error rate is too high and we need a complete performance.

"We are not going to focus on what others are doing, we will focus on our strengths and keep our feet on the ground."

Like the rest of the rugby league world, Hale was shocked to see the Kiwis booted out of the men's World Cup by Fiji and said they had sent their best wishes to the losing side.

"It was a shock and all of us girls were backing them. We are running completely separate campaigns to them and regardless of their result we have our heads down."

Hale works as a community manager for the Warriors and said the difference between the NRL team and the Kiwi Ferns camp is huge.

"Obviously the women's game is still growing and the NRL is so well established. I am hoping we get there one day. The training, the professionalism is all much the same, but our day looks a lot different to theirs. We go to work, train, go to work."

She was proud of her captain Laura Mariu, who is now in her fifth World Cup and having a crack at her fourth Rugby League World Cup title.

"That's amazing, I don't even know if men can match that."

After three pool matches, the Kiwi Ferns have conceded only one try and scored 164 points.

Kick off is at 3.45pm (NZ time). Australia's Jillaroos will face Canada in Sunday's other semifinal where another big score beckons after they beat them 88-0 on Wednesday.
