Gerrard said she and her team-mates will give their all to ensure they end the year with the upper hand on their major netball rivals.

"There won't be anything left in our tank after the game. It will all be out on the court," Gerrard vowed after the Diamonds levelled the three-Test series with a rousing 51-44 win over the Silver Ferns.

"We'll be fighting to the death.

"We want to leave the sport on a high note when this game is over."

Gerrard, on the comeback from a calf injury, was one of the stars of Wednesday night's win in Adelaide along with fellow veteran, shooter Catherine Cox.

Both players were motivated to perform at their best after admitting they felt they had played well below par in the Diamond's one-goal loss in Perth last Sunday.

"I really felt I had to redeem myself," Gerrard said. "I felt like I needed to get my head, my heart and my feet back in the game."

Cox was so impressive under the net she was awarded Player of the Match honours.

Gerrard said all players must be on their game to beat New Zealand in Sunday's Test, the final international outing of the year for the Diamonds, who beat the Silver Ferns by one in July to claim the world crown.

"Totally I believe we can win this," Gerrard said.

"We still have heaps of areas we can improve on, particularly in our turnovers.

"This will be a real ripper of a game. One of the epic ones I reckon.

"They will be going all out and so will we."

After the Test, players will return to their home states to begin summer training for next season's Trans-Tasman netball league.

Gerrard has rejoined her old club, the NSW Swifts, for the 2012 competition between the top teams from either side of the Tasman.
