Canberra Raiders returned to NRL action with a commanding 22-6 win over Melbourne Storm to maintain their 100 per cent record.

Last year's Grand Final losers got the better of the 2019 minor premiers, earning a third straight victory at the Storm's home ground.

George Williams pulled the strings in assisting tries for Nick Cotric and Charnze Nicoll-Klokstad, with the Raiders at full throttle following the two-month coronavirus-enforced hiatus. 

Jordan Rapana also got in on the act, with Joseph Tapine's last-gasp try the only score of the second half in Melbourne.

New Zealand Warriors set the bar high in an 18-0 defeat of St George-Illawarra Dragons.

The Warriors completed their first 44 sets in a stunning display, with Jamayne Taunoa-Brown, Eliesa Katoa and Kodi Nikorima touching down at Central Coast Stadium.

It is now three defeats from three for the Dragons, while this was a first win for the Warriors.

Cronulla Sharks are also winless from their opening three games, with Wests Tigers condemning them to a 28-16 loss.

Despite trailing 16-10 at the break, the Tigers ran in 18 unanswered points after the interval.
