A nine-strong contingent from the Wanganui Swimming Club start their campaign today at the National Age Group Swimming Championships.
Being held at the Kilbirnie Pool in Wellington, the age-group meet will see more than 600 swimmers from across the country compete.
There will be 10 sessions over five days, finishing on Saturday.
Wanganui coach Jane Lowe said six of their team have qualified in the top 10 of their events.
"However, with just a few seconds between swimmers, all will be striving to reach the finals and to produce personal bests."
