The Kiwi side were quick out of the blocks last night, holding a 10-point lead after the opening quarter. The Canadians were able to trim the gap to just three points at half time, before taking a one-point lead of their own into the fourth quarter.
Canada led by as many as eight points in the final quarter, however a spirited fight back from the Tall Blacks saw Webster convert on a three-point play to tie the game and send it to over time.
The Canadians were too good in the extra period and took a two-game sweep.
Tall Blacks coach Paul Henare was pleased with the return to a more typical Tall Blacks effort, based on energy, work rate and an up-tempo offence.
"That was a much better effort and playing at the required intensity at this level," he said. "That was really good to see the response, obviously we are still disappointed with the result, but knowing the way we can play against quality athleticism, length and what they were doing systematically, it was pleasing to see such a change in such a short turnaround.
"We have to keep reminding ourselves about how we do those things, through messages, conversations, watching video – it is a good reminder that we can play at that level. It is repeated messages about doing those same things over and over again."
The Tall Blacks fly out to China today and will play three more warm up matches before their World Cup opener against Brazil on September 1.
