- Researchers in Fiordland were shocked to capture a rare great white shark on video.
- The shark was spotted during a survey studying fish abundance and marine reserves.
- Footage collected will help assess new fishing regulations and marine conservation efforts.
A research team conducting an underwater survey in Fiordland recently made an exciting discovery when a great white shark appeared on their footage. The Department of Conservation (DOC) staff, along with researchers from Sea Through Science, were using Baited Remote Underwater Video (BRUV) equipment in Tamatea/Dusky Sound to study fish species in the area.
DOC Senior Ranger Richard Kinsey explained that the survey aims to compare fish populations inside and outside marine reserves, providing insights into how these areas support fish stocks.
“This information will also be helpful for assessing whether Fiordland’s new fishing regulations benefit fish stocks in the coming years," said Kinsey. “It’s a great opportunity to collect valuable data and to see what species are attracted to the bait.”
The team gathered over 200 hours of footage, capturing a variety of species such as hāpuku, blue cod, octopus, and various sharks. However, one sighting stood out.
Sea Through Science researcher Adam Smith was reviewing the footage when he spotted a mature male great white shark.
“The stereo BRUV uses two GoPro cameras in underwater housings. At the end of the day, we download the footage back on the boat to see what has been attracted,” Smith explained.
“While reviewing the videos, I saw a mature male white pointer shark turn up to the BRUV – it was quite a shock! We had been laughing about how cool it would be to see something like that. It’s very rare to get such great footage.”
The shark was seen approaching the BRUV equipment, curiously mouthing the bait pot before swimming away.
“It’s great to see these majestic creatures in their natural environment and to see how curious they are around the BRUVs,” said Smith. “We’ve only seen a white shark once before during our surveys, at the Kermadec Islands, the other end of New Zealand.”
The data collected will be analysed in the coming months to improve understanding of marine reserves and how fish populations are affected by fishing and environmental changes.
DOC encourages the public to report any sightings, captures, or strandings of great white sharks to sharks@doc.govt.nz or by calling 0800 DOC HOT.
