Meanwhile 22 swimmers from the North Shore club will compete tomorrow, many of them top New Zealand Age Group swimmers who will no doubt provide motivation for Northland's swimmers to better their own personal best performances.
Also attending are Auckland clubs United, Kowhai, West Auckland and Papatoetoe.
Northland is headed by a strong Northwave contingent which includes top ranked New Zealand age group and junior swimmers Melita Raravula, Callum Prime, Ellie Eastwood and Mia Gordon, as well as Bay of Island's Jeremy Elliot, Whangarei's Sam Bailey and Bream Bay's Kieran Swords.
Their main goal will be to better the rigid qualifying times for the the New Zealand Junior Division 2, national Age Group, and New Zealand Open Championships.
Racing resumes at 9am on Saturday morning, followed by another session in the late afternoon beginning at 4pm.
On Sunday the swimming begins at 9am with a short break before the final session in the early afternoon.
