A three-try performance from David Williams has given Manly a 27-12 win over the New Zealand Warriors in Gosford on Sunday afternoon.

The Sea Eagles winger scored in the 25th, 46th and 57th minutes in Manly's five try to two victory. Brett Stewart also scored a double for his side.

Glenn Stewart told Grandstand his side's recent prowess down the left flank meant the Sea Eagles were able to capitalise down the right in Gosford, with the Warriors' attentions overly focused on the opposite wing.

"The combinations are starting to get back ... and hopefully we'll keep on getting better," he said.

"When our left side is going so well as it has been over the past month, I think a lot of teams concentrate on that side, which then opens up our right.

"It was a physical [game], I don't know about comfortable, we didn't feel comfortable out there.

"We played really good in patches, but when we got down their end we weren't making them pay and giving them some easy metres out, so we'll have to fix that up."

The Warriors' Simon Mannering said his side would have to get its act together with its finals chances slipping away.

"Nothing short of a win is what we need from here on in. The last two weeks we haven't got it," he told Grandstand.

"It's all good stringing a few together early on in the year, but it counts for nothing if you don't finish the season right.

"It's back to the drawing board for next week against a Panthers side that was pretty impressive against us last time."

The first half was a close affair, with the Warriors pushing the home side through a number of early chances.

But they were made to rue their inability to take those chances when one of their attacks turned into a 100m try that was finished off by Williams to make the score 10-0.

The Warriors hit back on 32 minutes when a bust down the right by Manu Vatuvei set up Ngani Laumape for a try to the visitors.

The Sea Eagles took a four-point lead into half-time, but Williams's second and third tries gave Manly a 20-6 lead which set up the win.

Warriors half-back Shaun Johnson scored with just under 20 minutes to go, but Stewart quickly killed off hopes of a comeback with his second of the match on 64 minutes.

A late field goal by Daly Cherry-Evans completed the scoring.

Manly is now on on 31 points, consolidating the team's hold on a top-four spot ahead of the finals.

In contrast the Warriors lost the opportunity to push into the top eight with a win. They are still on 22 points in 10th spot.
