Competition starts at 2pm Friday with beach events and the heats of the ironman.
The main carnival day is Saturday.
“We’re looking forward to a good weekend with a senior crew,” Midway head coach Jack Gavin said.
“Swell conditions look like being really fun and the weather should be hot.
“Midway will have 19 athletes competing this weekend across all age groups and we look forward to seeing our Under-15 athletes racing at home.
“Tyson Ingoe has been training really well and he and Sam Matthews will be looking to feature in the Under-17 age group,” Gavin said.
“Lilla Hain, Sophie Warren and young German exchange student Ida Berg have been training really hard on the sprint track and I look forward to seeing them in action.
“Tyron Evans has been very consistent over the season and should be dominant in the open men’s age group.”
Gavin said he was looking forward to seeing his crew race hard while also having fun on their home beach.
“Due to our strong numbers and good culture, we should retain the Shield.”
Waikanae head coach Arna Majstrovic said her team were excited at the opportunity to race.
“Especially since the Eastern Regional Championships at Mount Maunganui had to be cancelled.
“It’s important that athletes are able to test themselves to see how they are tracking before the nationals in Ōhope next month.
“We have a small group, but they are all keen and enthusiastic to push themselves against other clubs.
“Sunday will be an exciting new format with mixed team races that will be challenging but fun.”
Wainui head coach Dion Williams is “super-excited” at the prospect of seeing their seniors in competitive action.
“They have all been training hard, leading our training groups and setting a very high standard for our junior team to look up to.
“The Fukushima-Hall brothers - Rori and Mako - are very strong ... fantastic all-rounders, who are good at everything. They will hope to be in the medals, especially in beach events, ironman and board races.
“In the girls [races], Klara Pauwells in the ski and beach events is coming along strong; Zyanja Rudge is very strong in the swims; Betsy Findlay is a little rocket on the sand and a great board paddler.
“We are super-excited to get some racing in before the national champs.”
