Netball: Pressure on Silver Ferns in Constellation Cup finale - Lisa Alexander

Australian Diamonds coach Lisa Alexander believes all the pressure is on the Silver Ferns, heading into the fourth and final Constellation Cup test in Wellington on Thursday.

Australia lead the series 2-1 and are in the box-seat to retain the trophy they've held since 2013.

But if New Zealand win by 14 goals or more, they will claim the title for the second time.

The Kiwis head into the match after beating Australia 55-44 in the third test, ending a nine-game losing streak against the current world champions.

The Ferns are desperate to show they're not one-hit wonders and claim back-to-back wins over Australia for the first time in nearly three years.

Alexander knows all the pressure will be on them, when the first centre pass is thrown.

"We might put a little bit of pressure on the Silver Ferns, and they need to back up and perform," said Alexander.

"They're at home and they have the home crowd behind them.

"They've shown progress anyway, so I think Noeline [Taurua] would be happy with this series. I'm sure they'll press their claim for the Constellation Cup.

"We don't want them to win it. It is not about the margin, it is about winning, so we need to put our best foot forward to ensure we stick to the game plan for 60 minutes."

Alexander said the team met with umpires to discuss the one-sided penalty count during the Hamilton test.

The Australians were penalised 81 times, compared to New Zealand's 45.

"We will look at some footage, and ask questions to clarify what we need to do and how we can perform better, without drawing the attention of the umpires.

"If we're getting penalised more than the opposition, there is always a concern, so therefore you have to ask the question.

“We've done that and I'm satisfied we've got the answers needed to adjust."
