Northlanders have until the end of the month to nominate people for this year's national Seaweek Ocean Champions competition.
The New Zealand Association for Environmental Education has extended the deadline for entries to January 31.
Ocean Champion contenders will be required to undertake a specific action to help solve a problem in the marine environment, in junior and senior categories.
Junior entrants will describe their challenge, and publicise it on their school blog or Facebook page, all entries going into a draw for prizes from Auckland Whale and Dolphin Safari and the Outboard Boating Club. Senior entrants will outline their challenge on the Seaweek website.
Voting is online during February and the winner will receive a prize package equivalent to at least $500 from the New Zealand Coastal Society.
