The orca is the largest member of the dolphin family and is often also called a killer whale.
When a pod of orca or marine life shows up, the port is guided by its marine mammal monitoring protocols that were developed as part of the resource consent process for the recently completed 6 Wharf construction project.
“This precaution helps to minimise the effect of underwater noise, even though the orca rarely swim into the port harbour itself,” the spokesperson said.
They said the shutdown on Tuesday this week allowed for a “safe and quiet passage” for the orcas swimming past the port. Normal business operations at the port weren’t impacted during the shutdown.
Napier Port said it was dedicated to ensuring the 6 Wharf project had a minimal environmental impact.
“As such, we committed to managing against any potential adverse effects throughout construction and dredging,” the spokesperson said.
“The Marine Mammals Protection Regulations 1992 also list the conditions governing behaviour around marine mammals, including vessels.”
The port had invested in a large body of scientific research on Hawke’s Bay’s marine environment to ensure the project was the best it could be for the environment, the spokesperson said.
“Throughout the project, we also worked with key stakeholders and followed comprehensive and best-practice management plans to protect the environment.”
Department of Conservation (DoC) marine technical adviser Hannah Hendriks said orca were regularly seen around New Zealand’s entire coastline this time of the year, where they could often be seen hunting rays and teaching their young how to hunt.
“We recommend, if you are lucky enough to see any orca, [keeping] your distance by keeping boats and kayaks 50 metres away, turning your engine off and enjoying the experience,” she said.
“Orcas are generally not aggressive towards humans. However, swimming with them is prohibited for the safety of both people and the orca. We’d appreciate anyone who spots them to report their sighting to DoC.”
In the summer of last year, a mother and son were privy to a spectacular aerial display performed by orcas outside their home on a Napier beach.
Amy Blakesley and her 11-year-old, Evan, were watching a pod of three swim close to the shore when one leapt right out of the water at Bayview, north of Napier.
Orca whale specialist Dr Ingrid Visser, of the Orca Research Trust, said at the time monitoring the animals was “very important” as there were fewer than 200 of them living around the New Zealand coastline.
