First orca pod spotted in Akaroa Harbour for 2017
Black Cat Cruises staff were delighted to spot a pod of 10 orca including two young calves in Akaroa Harbour yesterday
afternoon (Tuesday, 10 January).
This is the first reported sighting of orca off the coast of the South Island this month.
More than 80 local and international passengers aboard the 1.30pm Akaroa Harbour Nature Cruise rushed for their cameras
after Black Cat Cruises skipper Julian Yates sighted the pod near the Akaroa Lighthouse.
“The pod of orca we came across included one alpha male, a second male with a damaged dorsal fin, four females, two
juveniles and two calves that were approximately one or 2-years- old,” Yates said.
“The younger orca were curiously approaching and hanging around our cruise boat while the males stayed distant and led
the pod into Daemons Bay. It was here that we found the second male that was missing part of his dorsal fin. Dorsal fins
provide stability to orca when swimming but it didn’t seem to be affecting him.”
To ensure the viewing was safe and unobtrusive, Yates slowed down the catamaran at the first sighting and turned off the
engines in Daemons Bay so passengers could view and marvel one of the world’s largest apex predators. The engines were
also turned off when orca approached the back of the boat.
“Orca whales are very intelligent animals that are well-organised and follow highly complex social structures within
their pods which often consist of large groups of family members that can span several generations,” said Yates.
While there is not a typical orca migration season in New Zealand, Black Cat Cruises usually report a number of
sightings each year with the majority occurring in spring.
Staff can determine the sex of orca by analysing the mammal’s physical characteristics. Males typically grow between
seven and eight metres long and weigh up to 5.5 tonnes whereas females are smaller reaching approximately six metres in
length and up to 3.6 tonnes in weight. Males also have a distinctive dorsal fin up to 1.8 metres tall. The fin of
females is shorter (about 0.9 metres) and more curved.
Black Cat Cruises photographer Jonothan ‘Jono’ Hithcox described the encounter as “the best orca sighting we’ve ever
had” with the viewing lasting about 20 minutes.
“We imagine the orca went into the bay to hunt stingray,” he said. “On our return trip we saw a second pod that had been
spotted by another boat. We weren’t sure of the size of this pod as they were travelling north very quickly. Our
passengers also saw the Endangered Hector’s Dolphin on the tour so they got to see the world’s smallest and largest
members of the dolphin family.”
Black Cat Cruises’ passengers aboard the 3.40pm Akaroa Harbour Nature Cruise saw two pods of orca, along with a second
alpha male. The pod was described as being “even more inquisitive and playful, interacting around the boat”.
Yates recognised the second alpha male from the earlier orca sighting due to his distinct dorsal fin markings. This pod
was returning to Akaroa Harbour.
The first orca of the 2016 season were sighted in Akaroa Harbour by Black Cat Cruises in October.
Black Cat Cruises was the first eco-tourism operator in Canterbury to receive a Sustainable Marine Mammal Actions in
Recreation and Tourism (SMART) certification from the Department of Conservation (DOC) in 2015.
SMART is a voluntary collaboration between commercial boat operators and the DOC for the protection of marine mammals in
New Zealand. It aims to promote responsible behaviour around dolphins, whales and seals by boat operators.
