Waikato needed just 70 seconds from the kickoff to score through loosehead prop Toby Smith.
Canterbury failed to control the kickoff and Waikato took possession driving Canterbury deep into their 22 over a number of well-controlled phases which ended with Smith crashing over.
That started 24 minutes of misery for Canterbury as Waikato, with first five-eighth Stephen Donald kicking immaculately, halfback Tawera Kerr-Barlow sniping from behind the rucks, and backs Tim Mikkelson and Richard Kahui running well, took control.
Kerr-Barlow set up the second try after bursting through a gap, the forwards continued the momentum and it ended with lock Toby Lynn going over.
The third was again crafted by the halfback with a nice pass to Mikkelson to run onto in the 13th minute and with Donald's conversion, it was 19-0.
Canterbury struck back quickly with a scrappily conceived converted try to No 8 Nasi Manu but Waikato got their bonus point with the best try of the match.
Fullback Trent Renata launced a counter attack and it was carried on by wing Henry Speight who sent Kahui in to score with a sweetly-timed pass.
The second half was a dour affair with Canterbury doing very little to reduce their errors while Waikato were content to sit on their lead after Donald struck another penalty.
