Richie Mo'unga plundered a hat-trick as the Crusaders demolished the Reds 63-28 in Brisbane, with the champions of New Zealand swamping their Australian counterparts in Super Rugby Trans Tasman.

In just the second round of the competition, the Canterbury giants showed off their prowess and Mo'unga served up a dazzling offering of his quality.

The All Blacks fly-half was in inspired form from the off, and by the half-hour mark he had already snagged a pair of clinical tries and set up Sevu Reece to dart in for another stunning score. With Cullen Grace also sprinting through for a try, and Mo'unga clinical from the tee, the rampaging Crusaders were 28-0 ahead after just 29 minutes.

Tate McDermott got the Reds on the board with their first try, but the Crusaders kept the points flowing, Reece dashing in at the right corner to increase their lead to 35-7 early in the second half, before Mo'unga got his third try after 55 minutes, dotting down near the posts to allow himself an easy conversion.

A penalty try, accompanied by a yellow card for Harry Hoopert, nudged the Crusaders 49-7 ahead, but curiously the 14-man Reds then enjoyed their best spell, as Harry Wilson and Suliasi Vunivalu scored classy tries to reduce their deficit to 49-21 going into the final 15 minutes.

Hopes of further damage limitation were crushed when Tamaiti Williams powered over and Codie Taylor added another try to emphasise a devastating team performance, before Brandon Paenga-Amosa barged in for a last-gasp consolation.

Luke Jacobson earlier crossed twice as the Chiefs ran in six tries in a 40-19 victory over the Brumbies in Hamilton.

The hosts overwhelmed their visitors, with Jacobson landing a first-half double, collecting from the back of the scrum and crossing from close range each time, and further tries coming from Tupou Vaa'i, Damian McKenzie, Alex Nankivell and Anton Lienert-Brown.

McKenzie booted five conversions, with the result never in doubt. The Brumbies responded through tries from Len Ikitau, Tom Cusack and, right at the death, Rob Valetini.

Wing Bryce Heem grabbed a hat-trick for a rampant Blues side whose second-half dominance secured a 48-21 win against the Waratahs.

Armed with a 22-14 half-time advantage, the Blues raised their game for the second 40 minutes and pulled away, inflicting a 10th straight defeat of the season on the visitors to Eden Park.
