The New Zealand Warriors have opened their season with back-to-back wins for the first time since 2009, but coach Stephen Kearney knows his side can only get better.

The Auckland club ran in four tries in their 20-8 win against the Gold Coast Titans in front of over 14,000 at Mt Smart Stadium on Saturday.

The Warriors dominated most of the match, but 11 errors and a 69 percent completion rate prevented Kearney's side from scoring more points in the contest.

Kearney was glad to secure consecutive wins but admitted post-match that his side needed to show more composure with the football.

"The thing we're not getting carried away with is that I think we have a lot more improvement in us - we recognised that today in the sheds after the game, but it was a real tough grinding win and it was good to get the result," Kearney said.

"I thought we scrambled well and kept our shape together. I knew it was going to be a really tough week, coming back from a big trip so it was really about focusing on getting our jobs done and I thought the boys did that pretty well.

"It was a real tough contest and what I liked about the lads' performance is that they stayed in the battle and Roger (Tuivasa-Sheck), again, came up with some really big plays."

Captain Roger Tuivasa-Sheck was once again inspirational at the back, making some crucial try-saving tackles, and running 215 metres with the ball.
