Penrith Panthers have made their best start to a season since 1997 after beating New Zealand Warriors 26-0 on Friday to go top of the NRL ladder.
The inexperienced half-back pairing of Matt Burton and Jarome Luai shone in the absence of the suspended Nathan Cleary to ensure the Panthers remain unbeaten after four rounds.
Burton touched down twice in the opening 22 minutes at Campbelltown Stadium, scooping up a loose ball following a high kick for his first try before profiting again after blocking Blake Green's kick.
Luai collected his own kick to add a third try and second-half scores from Josh Mansour and Billy Burns completed the rout.
While Penrith have enjoyed a fine start to the season that has included three wins and a draw, South Sydney Rabbitohs' disappointing 2020 continued as they were beaten 22-8 by Melbourne Storm at AAMI Park.
In the battle of the full-backs, Ryan Papenhuyzen's try put Melbourne on the board before Latrell Mitchell, playing his 100th NRL game, responded with a tremendous pass that enabled Alex Johnston to go in.
Suliasi Vunivalu restored the Storm's lead after brilliant work from Cameron Munster, though, and after Adam Reynolds and Cameron Smith traded penalties, Josh Addo-Carr collected Munster's kick to increase the home side's lead.
Justin Olam's try three minutes from time completed the scoring as the Bunnies, who remain without a victory in Melbourne in 16 attempts, slipped to a third straight loss.
