A local principal will sport a skimpy two-piece mermaid costume when he plunges into the icy depths of Tikitapu (Blue Lake) this weekend.
Westbrook School principal Colin Watkins is no stranger to dressing up for a good cause and this year he has issued a challenge for all local principals to do the same in support of Rotorua's Life Education Trust.
The trust is holding its annual Dunk for Harold fundraiser at the Blue Lake on Sunday where local schools, sports teams, emergency services and businesses nominate teams to jump into the lake to raise money for the trust.
Last year the trust raised around $7000.
The non-profit organisation teaches a wide spectrum of health topics to primary and intermediate school children.
Mr Watkins said his school had been taking part in the fundraiser for around eight years.
"I'm a big supporter of the trust and we like to do everything we can to drum up support so I'm putting out the challenge to all the other schools to come down to the lake, dress in whatever you like, and take a dip for the trust."

He said for a gold coin donation this year pupils were given the chance to vote for which costume he would wear when jumping into the lake.
"The mermaid won and I can tell you it's going to be freezing because I don't wear a wetsuit and it's quite skimpy."
Westbrook School pupils Stuart Thurlow, 8, Paige Waitoa, 8, Annalise Drabble, 9, and Paige Dudson, 9, are also preparing to make the big leap.
"My favourite part about taking part in the fundraiser is being able to support the trust and everyone seeing my costume," Paige Dudson said.
Stuart agreed, saying he could not wait until everyone saw him dressed up as a stormtrooper.
Trust chairwoman Jules McLaughlin said last year's event was so successful and they were hoping for the same level of support this year.
"We have about 45 dunkers confirmed so far and we just heard back from the local fire service who are going to take part.
We're hoping more people will come on the day because it's quite special seeing all these crazy people in outrageous costumes jumping into the lake."
