He said Dr Visser stood out among the world's orca experts for her passion and the quality of her research, despite limited resources.
"She has a total passion for marine life. I haven't met anyone else who's quite so single-minded, so as a subject she's a joy and a privilege to follow," he said. It was also unusual for a scientist to have such a high public profile.
"She's a bit of a rock star," he said.
Dr Visser's research had revealed high levels of pollutants in the orcas' bodies, often from substances that had been banned long ago, threatening an already small population.
Dr Visser is pleased the documentary will finally be seen in her home country, being screened on TV3's 60 Minutes at 7.30pm on February 12, and she thanked the public for all their support of her work over the years.
