map-nzWho we are

Blue Water Marine Research Ltd (1997) was established by John Holdsworth and Peter Saul who together, have over 50 years experience in fisheries management and research. The business in based near the small fishing port of Tutukaka in northern New Zealand but projects have been undertaken around the country, from Fiordland to Wanganella Banks.

There have been many technological advances in the way marine species are studied and Blue Water Marine Research is a leader in the use of electronic fish tag technology in New Zealand. Fisheries management has also advanced.

The Quota Management System (QMS) has been effective in rationalising the commercial fleet but employs complex decision making and consultation processes. A good understanding of the legislative and research requirements is important to get the best results. We have considerable experience in fisheries research and management systems in New Zealand. This depth of knowledge has been useful in providing quality research and advice on fisheries and marine issues.
