After a blip during level 2, entries are back on track and Adsett expects more than 200 people will participate.
He expected "a rush of online entries" today and possibly some late entries tomorrow.
Originally created to fundraise for the Napier Aquahawks Swim Club, the ocean swim is now a "real community sporting activity" in association with TriHB, Surf Lifesaving Hawke's Bay and Sport Hawke's Bay and now with a number of sponsors.
"That's what keeps me doing it even though I'm not involved with the club any longer - I just think it's a great thing to do."
Adsett says ocean swimming is becoming increasingly popular, notably at Ahuriri.
The first race begins at 9am on Saturday and Adsett encourages people to come and watch.
The four race distances with a kids' 200 metre dash, 500m, 1 kilometre and the popular 2.5km swim.
Late entries can be registered at the race pack collection at East Pier tomorrow between 4.30pm and 6.30pm.
