Duncan was forced into a string of saves throughout the contest as McDonald Jones Stadium where the Jets win boosted their top two aspirations.

"I think you've got to be ready for anything in those situations," Duncan said.

"The boys defended well as a unit tonight. I did have a bit to do but that's because we play open and expansive football and we want to be attacking.

"That comes with the way we want to play. I'm happy to do my bit as long as we're winning games."

The result comes after a draw and a loss for the Jets, who are seven points clear of third-placed Melbourne City.

"I think the last two games the results haven't been exactly what we wanted, only picking up one point, but the performances have been there," Duncan said.

"Maybe not so such against Wellington but against Melbourne City we still played some good football.

"We're playing well and building for the finals. That's what the boss keeps talking about."
