Doubtless Bay Marine Protection Group (Inc.Soc.)





Our Group was born in 2003 from a desire to restore and protect for future generation the natural marine heritage of the Doubtless Bay Area. We aim to make a difference. We invite you to join us, guide us, and support us in our vision of a restored and sustainable future.

Discussion Document Questionnaire Results




  • We aim to get representatives from all local community groups, hapu and iwi, to work together to protect and restore our marine environment in Doubtless Bay.
  • To raise public awareness about our marine environment as it is now and how it used to be in the past.
  • To prepare an overall plan for improved coastal marine management in the Doubtless Bay/ Tokerau area.
  • To express Kaitiakitanga/ guardianship for our local marine area.



  • There is virtually no local management or control of our marine environment.
  • Recreational fishers do not have priority over commercial fishers.
  • Some commercial fishing methods are severely detrimental to our local fishery eg gill netting, long lines.
  • Present fishing regulations do not  recognise seasonal changes eg spawning seasons.
  • The Quota Management System implemented by Ministry of Fisheries to preserve fish stocks is failing the total ecosystem.
  • Scallop/ tupu beds have been decimated by commercial dredging and siltation eg Mill Bay and Tokerau Beach.
  • Land catchment management directly    affects the water quality of our streams, rivers, harbours and sea  eg siltation of harbours and estuaries, fecal contamination of estuaries and beaches affecting shellfish gathering and swimming
  • Fish, shellfish and crayfish (both rock lobster and packhorse) stocks are well down on several generations ago.
  • Biodiversity has declined, top trophic feeders such as larger pack horse crayfish, resident kingfish in Mangonui Harbour, barracuda, hapuka are rare.
  • There are increased areas of "kina barren" where kelp forests have been reduced to rocky desert. The main cause is a severe reduction in top feeders eg large snapper and crayfish that kept the ecosystem balanced by consuming kina. The kelp forests were the nurseries for young fish and paua, while also harbouring stocks of crayfish. As kina barrens expand, the population of paua, juvenile fish and crayfish have been seen to decrease.
  • There is a lot of rubbish on the sea floor and harbours eg lead sinkers, old fishing line, nets and household refuse.
  • The proposed "aquaculture  management areas" are large and randomly sited.
  • Mangonui Harbour water flow has been badly affected by the road causeway linking Paewhenua Island to the mainland.
  • There are few marine educational opportunities for our young people and community. The closest untouched marine environments are the Goat Island Marine Reserve at Leigh and offshore at the Poor Knights Islands.
