Executive Committee Members

Jill Bradley (Chairperson/ Caretaker)

Director and co-founder of AgriSea NZ Seaweeds

Jill was a founding member of SANZ. She established Ocean Organics which manufactures NZ seaweed products for home gardeners in the early 1990’s and AgriSea New Zealand in 2004 which manufactures NZ seaweed - based nutrition products for the agriculture, horticulture, viticulture, and apiculture sectors.

Jill recognises that a long-term sustainable seaweed industry can only be built after a robust management plan for the seaweed fishery under the QMS is in place. For over a decade her family funded a research project which examined the environmental effects of wild harvesting seaweed from the marine coastal eco-system. Out of this research comes recommendations for a safe harvest plan on which a seaweed industry can flourish for New Zealand.

Dr Ian Miller (Vice Chairperson)

Ex Managing Director of Carina Chemicals Laboratories Ltd.
BSc (hons 1), PhD, FNZIC, FRSC

Another key member of SANZ, Ian worked in the Chemistry Division at DSIR for close to 20 years (1971-78 researcher, 1978-85 Section Head, 1986 Group Leader). He then left to become Managing Director of Carina Chemical Laboratories Ltd. Currently, he does some consulting work and in a semi-retired state, spends time on theoretical work and on writing and self-publishing. Ian is a widower who currently lives in Lower Hutt with Horatio, his Chief Rodent Extermination Officer.

His scientific research has fallen into the following (order unimportant):

  1. Phycocolloid research involving structural aspects of red seaweed polysaccharides, and selected fucans. Various techniques were developed, mainly using 13C NMR, where, provided conformation is constant, the change of signal position due to substitution can be assigned due to assignable small changes of magnetic vector potential through the small diamagnetic effects. New processes have also been developed for making commercially desirable products based on algal phycocolloids, one of which is licensed to Nemidon Ltd, and is the basis of their commercially available skin gels.

  2. Photochemistry and free radical work has covered a range of chemistry and applications, from lignin structure, sunscreens , to the protection of fabrics from photodegradation and the protection and conservation of fabric artefacts.

  3. Work on energy from biomass and wastes commences due to the 1970’s energy crises at DSIR, but progressed to examining pyrolysis of biomass, and then to high pressure liquefaction of biomass to make fuels and chemicals.

  4. Carina Chemical Laboratories Ltd was established primarily to provide scientific research for a joint venture to make pyromellitic acid from durene, on polyimides, and on other potential chemical derivatives. This failed when the government sold Motunui, and the durene was no longer available.

  5. Theory. Chemical Strain theory was developed to explain the unusual reactivity and properties of strained molecules. Planetary formation was proposed to be due to chemical effects in the accretion disk, the details of which are in the ebook “Planetary Formation and Biogenesis”. Finally, an alternative interpretation of quantum mechanics was developed, similar to the pilot wave but with two further additions, and this has been used to provide a much simpler means of calculating the properties of chemical covalent bonds.

Clare Bradley (Treasurer)

Business Development Manager of AgriSea NZ Seaweeds

Clare has been the Secretary and Treasurer of SANZ from 2006 to 2018. Clare is passionate about the environment and working with community groups. After starting her biology degree at Auckland University Clare took time out to spend 2 years in the remote amazon rainforest working on science expeditions with volunteer groups and local indigenous communities to establish environmental protection and economic development for the community.

Clare is now part of the second generation of family members to run AgriSea. Her role at AgriSea is diverse and she connects to all aspects of the seaweed value chain through their family business.

Ashleigh Browne (Secretary)

R&D Manager of AgriSea NZ Seaweeds

Ashleigh developed a passion for the marine environment at an early age. She spent much of her childhood at the beach or the bush, and later chose to pursue a tertiary education in the Biological Sciences. 

Ashleigh’s qualifications include Diploma in Marine Studies at the BOP Polytechnic, and a BSc/ MSc in Biological Sciences at University of Waikato. Her masters research - funded Zespri, Plant Food Research, KVH, and UOW - examined potential bioactive compounds in seaweed for management of the kiwifruit pathogen Psa. She has worked for Regional Council, Crown Research Institutes, and organisations in the bioactives/biostimulant industry.

Paul Houston

Owner/Operator P&S Seaweed Harvesters

Paul Houston is a descendant of Te-Whanau-A-Apanui iwi, born and raised in Waihau Bay on the East coast of the north island of NZ.

He has 24 years experience in the fishing industry - 8 yrs as a tuna long liner and 16 yrs working and managing a local team of contractors undergoing investigative research studies, creating robust wild harvesting protocols and fabricating equipment to harvest Ecklonia Radiata Seaweed, concomitant with developing his own seaweed business from NZ beach cast seaweeds with his wife Simone Rankin who are equally passionate about contributing to the success and growth of the NZ seaweed industry with the vision and goal to open long term locally owned sustainable employment along the East Coast of NZ.
