A video recorded by Dylan Brayshaw's camera drone at Hahei Beach shows lone swimmer Judie Johnson being approached by the aquatic mammals. Advertisement Johnson said she initially mistook the orcas for dolphins until she noticed their coloring. The swimmer said she was concerned the killer whales might mistake her for a seal due to her black wetsuit, but the experience ended up being a positive one.
