Napier's young Marineland Rangers groups have finished runners-up in the inaugural 2014 Ocean Champions national contest staged as part of Seaweek.
"They are pretty stoked about the result despite not winning outright," said Emily Otto, the mother of Brianna Otto who leads the youngsters aged between 4 and 14.
"They did extremely well and we are very, very proud of them and their efforts."
The group went up alongside about 20 other entrants from throughout the country and the standard was high, Seaweek coordinator Dr Mels Barton said.
"The Ocean Champion initiative celebrates all those individuals, groups and organisations who work so hard to look after our seas and the marine life that lives in them," Dr Barton said.
