Warriors coach Stephen Kearney saw enough positives to be pleased with his side's performance at Rotorua International Stadium, despite a slow start.
The Warriors let the Melbourne Storm in for a soft try within three minutes on Saturday, but they grew as the game went on and won 20-14.
It was not a blow-out win by any means, but Kearney was in a good mood post-match.
"I thought there were some really nice patches there from the boys, in terms of expectation this early. There were probably some patches that weren't as tidy and we need to improve on, but I was quietly pleased.
"I thought a couple of their tries were softies, all of them to be fair, but that's a little technical detail which I think we can fix pretty easily. For the most part I thought the defence was pretty good and there were some promising signs," Kearney said.
