Ravn said mums and pups have been targeted in particular, because they’ve been in closer proximity to people and popular beaches.
In the Dunedin area, she said, there was “a small population of only a couple dozen pups” who are being put under intense pressure when people flock to the beach on sunny days.
There have also been ongoing issues with parents leaving their children alone and near sea lions to capture photos and dog owners letting their pups run off-lead to harass the animals.
New Zealand sea lions are one of the rarest sea lion species in the world and are listed as being nationally vulnerable.
“We’re seeing so many things posted in breach of the Marine Mammal Protection Act all the time,” Ravn said.
She warned the harassment creates risks of having young pups grow up “feeling that humans are breaching their boundaries” – leading to aggressive behaviour.
While many would be quick to assume uneducated tourists are largely responsible for the poor interactions, Ravn said that is not the case.
“The reality is this is locals as well – who’ve grown up along[side] sea lions – and should know way better than [the behaviour] they’re displaying.”
Ravn had four simple words of advice for people on how to deal with the animals.
“Just give them space.”
She said people should be staying at least 20m away, as signage should clearly state around areas with sea lion populations.
Ravn remained grateful to those in the community who have been doing their part in calling out, filming and educating others harassing sea lions when spotted.
She said those actions have been key in mitigating sea lion disturbance within the area.
Ravn encourages anyone who spots poor behaviour with sea lions to report it to authorities.
