Our Seas Our Future is holding a series of cleanups nationwide for Seaweek 2020, which this year is being held from February 29 to March 8.
The cleanups targeted one of the most discarded items in the world, cigarette butts.
In Dunedin about 15 people took part in a cleanup on Saturday around the University of Otago and the Otago Museum.
More than 300 litres of rubbish was picked up alongside the 4000 cigarette butts.
Our Seas Our Future founder Noel Jhinku said he saw large concentrations of cigarette butts around seating areas where Smokefree signs were on display.
‘‘Responsible litter management not only includes properly disposing of rubbish into bins, but also to consider and be conscious of how we can reduce the amount of rubbish we are generating in the first place.’’
Mr Jhinku said the impact of a cigarette butt had wider consequences for the environment.
‘‘It's a negative impact on your health, and the environment.
‘‘While we certainly don't endorse smoking, if you are going to smoke, carry a pocket ashtray with you.’’
Another cleanup will be held on Saturday in conjunction with Keep Dunedin Beautiful at St Kilda.
