The Department of Conservation (DOC) is urging boaties, kayakers, and jet-skiers to respect marine mammal protection laws following multiple orca sightings in Waikato’s Raglan and Kawhia Harbours. Reports of vessels getting too close to the animals – and in some cases actively pursuing them – have raised concerns about both human safety and the well-being of these highly threatened marine predators.
Close encounters with orca
Over the past two weeks, a family pod of five orca has been sighted in the two harbours. These magnificent animals, which form part of New Zealand’s resident population, are believed to be feeding in the area. While their presence has sparked excitement among locals and visitors, DOC Marine Species Manager Malene Felsing warns that inappropriate human interactions can have serious consequences.
DOC has received reports, including social media complaints, about boats and other watercraft getting too close to the orca. In one incident, a vessel was allegedly chasing the pod in Raglan Harbour.
“The orca pod is bringing people a lot of joy, which is great,” says Felsing.
“However, this family group includes a large male and an adult female – these are powerful animals who could do serious harm if agitated.”
The pod also includes calves, which are particularly vulnerable to injury or disturbance, including potential separation from their mothers. Felsing stresses that while orca may approach vessels on their own terms, boaties should never initiate contact.
The risks of human disturbance
Orca are apex predators, but their numbers in New Zealand waters remain critically low, with an estimated population of only 150 to 200 individuals. They are classified as Nationally Critical under the New Zealand Threat Classification System. One of the biggest threats they face is human disturbance, which can disrupt their feeding, resting, and social behaviours.
New Zealand’s marine mammal protection rules are clear:
- Vessels must stay at least 50 metres from orca at all times.
- A maximum of three vessels are allowed within 300 metres of orca at any given time.
- Kayaks and paddleboards count as individual vessels unless they are rafted together.
If orca approach a vessel, the best course of action is to turn off engines, remain still, and simply enjoy the encounter until the animals move on. Chasing, circling, or cutting off their path is strictly prohibited and could result in legal action.
Legal consequences for rule breakers
Under the Marine Mammals Protection Act 1978, it is illegal to harass, disturb, injure, or kill marine mammals. Those found guilty of violating these laws face serious penalties, including:
- A maximum fine of $250,000 or up to two years’ imprisonment for offences involving harm to marine mammals.
- Potential infringement fines for getting too close or failing to comply with distance rules.
In May 2024, a man was fined $600 after video footage emerged of him attempting to leap onto an orca in Auckland waters. DOC is urging people to learn from such incidents and act responsibly.
Reporting orca harassment
Anyone witnessing harassment or disturbance of orca or other marine mammals should report the incident immediately to DOC by calling 0800 DOC HOT (0800 362 468). Providing details such as the location, time, and any identifying features of vessels or individuals involved will help authorities take appropriate action.
“We want marine mammals like orca to be able to go about their natural behaviours such as feeding, socialising, and resting,” says Felsing.
“Improper interactions can severely disrupt this kind of behaviour.”
Enjoying orca responsibly
Orca sightings are a privilege, offering a rare chance to observe one of the ocean’s most intelligent and powerful creatures in their natural habitat. However, these encounters come with a responsibility to respect the animals and follow the laws designed to protect them.
For those lucky enough to witness orca while out on the water, the key takeaways are simple:
- Observe from a safe distance – at least 50 metres away.
- If orca approach you, stay still and let them decide the interaction.
- Never chase or attempt to touch the animals.
- Report any illegal behaviour to DOC.
By respecting these guidelines, boaties can help ensure that New Zealand’s orca population continues to thrive, while also keeping themselves safe.
