There will be a sausage sizzle and other food vendors, and children can have photos taken with Santa and Disney princesses Anna and Elsa.
The event will be followed by Christmas carols at 5.30pm.
Newitt said sadly it was not possible to organise another parade due to scheduling issues and the times that participants are available to take part.
"Unfortunately there are very few alternative days we can do due to events happening in the city centre over the next few weeks," she said.
"Many of the participants aren't able to reschedule for an alternative day."
Tauranga was not the only parade to be rained off this year - the Seeka Te Puke Christmas parade planned for December 1 was also canned.
There were hopes of the Te Puke parade being rescheduled. The Western Bay of Plenty District Council was looking at holding a parade on December 15, but had yet to confirm the date.
