Led by sparkling halfback Shaun Johnson and flying winger Glen Fisiiahi, the Warriors scored nine tries to one in the pre-season match.
The Warriors backs found plenty of gaps to exploit and could have scored another two or three tries.
Providing the platform were workhorses Simon Mannering and Nathan Friend.
The Broncos struggled to create many try-scoring opportunities and showed a lack of accuracy on attack.
It may only have been a pre-season game but it was a nice boost for the Warriors ahead of their NRL season opener against the Parramatta Eels on March 9.
Warriors 48 (Glen Fisiiahi 2, Konrad Hurrell 2, Shaun Johnson, Charlie Gubb, Carlos Tuimavave, David Fusitua, Sam Tomkins tries; Johnson 4 goals, Chad Townsend 2 goals), Broncos 4 (Jack Reed try). HT: 22-4.
