Dr. Ingrid N. Visser – Whale Rescue Co-Founder
Ingrid has attended numerous mass and individual strandings. She is experienced in sampling and data collection at these events, and in the use of refloatation Rescue Pontoons and other rescue equipment. She has served on the Board and was a trainer for another stranding rescue group.
Ingrid began studying NZ orca in 1992, going on to complete the first and only PhD dissertation on this population. Since then, Ingrid has become an internationally-acclaimed authority on orca, having established research projects and studied orca in Argentina, Papua New Guinea, Iceland, Antarctica, Russia, North America and, not least of all, NZ. Ingrid founded and to this day still runs the Orca Research Trust, Adopt-an-Orca, AKWIC (Antarctica Killer Whale Identification Catalogue), Punta Norte Orca Research, and Papua New Guinea Orca Research.
She is an accomplished wildlife photographer, as her many awards attest to, a PADI Dive Instructor, and a commercial skipper. Ingrid has been instrumental in introducing the public to wild orca and their lives through her countless TV appearances, starring roles in documentaries, and popular articles in magazines, not to mention her two children’s books and autobiography.

New Zealand rescuers try to reunite stranded baby orca with pod
Hundreds of people have joined the search for the killer whale’s pod, with rescuers hopeful his family will return for him
Animal rescue teams in New Zealand have begun trying to reunite a baby orca with its pod after it was found stranded near Wellington.
A pair of teenagers found the male calf caught in the rocks near Plimmerton, north of the city, with minor injuries, on Sunday afternoon.
Rescuers from the Department of Conservation (DOC) and volunteers from the Orca Research Trust have been taking shifts, in freezing temperatures, to care for the calf since it separated from its pod.
The rescue teams were forced to relocate the mammal into a makeshift enclosure on Sunday night when attempts to find its pod failed. It has since returned to a fenced off section in the ocean.
The local iwi (tribe), Ngāti Toa, named the roughly six-month old calf Toa, meaning “strong” or “brave”, at a ceremony on Tuesday morning.
Dr Ingrid Visser, the founder of the Orca Research Trust, told Australian Associated Press she had not lost hope of finding Toa’s family.
“Orcas travel between 100 and 150 kilometres a day but they don’t go in a straight line. They could turn around and come back here tomorrow. We just don’t know,” Visser said.
The roaming nature of the animal means if a killer whale pod was found, it was most likely to be Toa’s family, she said.
The DOC is urging the public to report any sightings of orca pods.
Hundreds of Wellingtonians have joined the search, with locals stationing themselves at headlands, walking the coastline and searching by boat or air. The hunt for the calf’s pod has even extended up to Whanganui, nearly 200km north of Wellington.
The DOC said one pod has been sighted in Marlborough Sounds, at the top of the South Island, roughly 100km south-west.
If Toa’s family cannot be located, the next step would be to search for another pod with calves. Orca mothers are known to adopt babies that are not their own, providing they are lactating, Visser told AAP.

Arrow and Bling: A Successful Dolphin Rescue in New Zealand
Dr. Ingrid Visser is one of the foremost experts on orcas in the world, having studied them extensively in New Zealand through her Orca Research Trust . She has worked on marine mammal research and protection all around the world, including working with the International Marine Mammal Project of Earth Island Institute. We are pleased to bring you this special report from her about the successful rescue of two stranded dolphins.
On 10 Dec 2020 two male dolphins (Arrow & Bling) became stuck on the mudflats in the Mahurangi Harbor.
Recently, while out on the Orca Research Trust boat, the Whale Rescue and dodoland (EUGY) teams spotted a group of dolphins heading north, near Whangarei Heads. Within just moments of them approaching the boat, we recognized Arrow and immediately began taking photos, in the hopes of documenting him. As soon as we captured him on camera, we sent the image off to Joanne (Floppy) Halliday (who has been documenting the dolphins in the Bay of Islands for over 30 years), to confirm it was him.
While that was underway, we kept taking photos of the other dolphins (at least 15 in the group) and sure enough, we found Bling too (Floppy has also confirmed the match for him).
The distance between the two locations – the site of the stranding and the area of re-sighting the pair – is only 90 km, so it is unlikely that they have remained in this small bit of coastline for the past 90 days. Although the Bay of Islands is a zone that these dolphins commonly hang out in, we are not aware of any sightings of either Arrow and Bling in that area since the stranding. So, it remains a mystery as to where they have been.
The other dolphins they were traveling with during their re-sighting are well known, and they have been seen with Arrow and Bling many times before. Like Arrow and Bling, they also spend a lot of time in the Bay of Islands.
Several studies have looked at the survival success after rescue for stranded dolphins. One aspect that is considered important is if an animal reintegrates with its social network. We can certainly confirm that is the case here, for both Arrow and Bling!
We again extend our thanks to all those involved in the rescue of these two dolphins – and emphasize that taking photos of all stranded whales and dolphins is a vital part of the rescue, especially photos of those parts of the animal that are identification keys, to confirm that the individual has survived.
The International Marine Mammal Project has posted a series of blogs about other successful release programs for dolphins and whales:
"Dolphins Held Captive For Decades Successfully Released"
"The Welcome Home Project of 1990 Send More Dolphins to Freedom"
"The Springer Introduction"
The International Marine Mammal Project continues to work to improve the survival of whales and dolphins, with emphasis on ending whaling and dolphin hunts, ending the captivity of whales and dolphins, cleaning up plastic pollution, stopping the entanglement and drowning of cetaceans and other marine life in fishing nets and lines, and protecting the ocean habitat from offshore oil drilling and other impacts. We hope you will donate to our work to continue the protection of whales and dolphins around the world. Thank you!

Ingrid Natasha Visser (born 20 February 1966) is a New Zealand marine biologist who studies orcas. She regularly lectures on the subject aboard cruise ships, especially in Antarctica, and has been featured in several documentaries about orcas. Early life Visser was born in Lower Hutt, Wellington, New Zealand.
Researchers are still discovering facts about New Zealand's orcas. For example, more have damaged dorsal fins than orcas in other regions, although the reason is not known. Where do they live? There are three main groups.

We present the first fine-scale data relating to the occurrence and group characteristics for killer whales ( Orcinus orca) in the Hauraki Gulf, New Zealand, as observed from a platform of opportunity (PoP). Group size and composition were examined in relation to water depth and sea surface temperature (SST).
In New Zealand, killer whales are documented to regularly feed on stingrays [106] and sharks [107,108], with marine mammal predations also recorded [109]. In locations where prey specialisation ...

However, to date, no research project has identified large populations in any one area. Do orcas have teeth? Orca are one of the toothed whales (Odontoceti), as are other dolphins and porpoises, pilot whales and sperm whales etc. Orca have 10 to 13 pairs of interlocking conical teeth in the upper and lower jaws, usually with a total of 48.
