NRL: Winning NZ Warriors retain unchanged line-up against hurting Sydney Roosters

NZ Warriors coach Andrew Webster has shown faith in the players that won their season-opener, naming an unchanged line-up to face Sydney Roosters on Saturday.

Edward Kosi retains his spot on the wing, after replacing Kiwis international Dallin Watene-Zelezniak in the build-up to last week's victory over Newcastle Knights. The club is taking a cautious approach to Watene-Zelezniak's calf tear, targeting a return to play in round five against Cronulla Sharks.

Kosi, 24, celebrated his promotion to the starting line-up with his eighth try in his last eight appearances and 10th in 17 games for the Warriors. 

Perennially ranked among premiership favourites, the Roosters have been rocked early, suffering a surprise defeat to the expansion Dolphins in their inaugural game at Brisbane.

"We've got to be better, we know that," said star half Luke Keary. "We've got to be better straight away."
