At Lake Karapiro, the club members will take part in 200m, 500m and 1000m distance races, entering K1 individuals and K2-4 teams from Under 14 level right through to Masters.
It is expected the stars of the show will be the club's New Zealand teenaged representatives - Erica Tanner, Toby Brooke, Aiden Nossiter and a returning Max Brown from Victoria University - before they depart for the 2015 Australian GP 2 competition in Sydney.
However, club member Lisa Chase said they will have plenty more on show than just those standouts.
"We've got a few others, our medal tally will be wider spread."
Tim Rowe has been a contemporary of Nossiter and Brown in the team races and will do so again.
Racing begins this morning and continues to till Sunday afternoon.
The club had been a real buzz this season, said committee member Peter Brown.
"We have just had a fantastic summer for paddling conditions and the numbers turning up are growing continuously.
"As such, this year's nationals is a full three days of competition rather than the usual two-and-a-half and record numbers are competing."
After these nationals, the club will be looking for new members to join the club for 10.30am Saturday introduction sessions.
