Ms Catherall said her three school-age children had to support Canada until they lost and then the children could support New Zealand.
The family, who were all wearing Canadian T-shirts, aside from Mr Catherall who had on a New Zealand T-shirt but waved a Canadian flag, was planning on watching some of the games on television over the next two days, Ms Catherall said.
Today's parade was great because of the atmosphere and because they did not have to take their children out of school for it, Mr Catherall said.
Just down the road was 6-year-old Thomas Gee, who was waving a large Welsh flag as he patiently waited for his favourite team to come down Lambton Quay.
One of the first supporters to turn up for the parade, Thomas and his father had a prime spot right on the edge of the road.
Thomas, who had watched the parade last year too, said the best part about rugby was watching tries being scored.
Tickets for this weekend's tournament sold out within three minutes late last year.
The tournament, known just as much for the party as it is for the rugby, kicks off at 1pm tomorrow, with the final game played at 9.30pm on Saturday.
