As part of the WWF Conservation Stamp Collection, Niue released on 5 September 2012, a set of stamps celebrating the giant sea fans. These fans can grow up to spans of 2 metres, and can be found from depths of 10 metres down to 50 metres. Neither the stamps, nor the accompanying souvenir sheet, contain any designs related to scuba diving, however, the first day cancellation for this issue features a scuba diver, to reflect a major tourist experience in Niue.
