After DOC Biodiversity Ranger Jemma Welch was notified about the stranding at 12:00pm on Sunday, November 22nd, she explained that due to the remote location and a power outage making it difficult to contact people, it was 3:00pm by the time rangers arrived at the scene at Waitangi West Beach.
“Only 26 of the whales were still alive at this point, the majority of them appeared very weak, and were sadly euthanized due to the rough conditions of the sea, and almost certainty because of great white sharks in the water which are brought in by a stranding like this,” Welch said in a statement.
Sadly, two more whales had stranded by Monday morning and had to be euthanized when a team of DOC staff made a follow-up visit to the site.
“Bad weather and rough seas, with dirty water, reduced visibility, and sonar effectiveness, could confuse whales and dolphins,” the DOC explains on its website. “Mistakes while chasing prey in shallow waters are thought to be a major cause of strandings for orcas and dolphins. Conversely, large predators such as orcas might cause other marine mammals to panic and strand.”
The largest recorded mass stranding in New Zealandwas in 1918 when an estimated 651,000 pilot whales stranded on the Chatham Islands.
