"The seal has moved away from the crowds to the other side of the Whakatāne River, but was still visible from the Whakatāne Yacht Club where he has been spending a lot of time."
On the Momoa the sea elephant Facebook page, people said they had spotted the seal on Sunday.
A photo taken by one woman showed a tan-coloured mass on the riverbank. The woman said DoC staff had confirmed it was the seal.
Glaser said Momoa's new coat of fur could appear tan if it was dry. "It changes to a darker colour when it gets wet," Glaser said. "It appears he is still going through the moulting process."
It is hoped that once he completes the moulting period, he will make his way towards cooler water.
"But for the time being it appears he is still enjoying the sunny Eastern Bay."
While he remains, DoC has asked that people respect the cordons that have been put in place, give the seal the space and respect he deserves, and to enjoy the spectacle of having him here.
It is an offence under the Marine Mammals Protection Act 1978 (MMPA) to disturb, harass, harm, injure or kill a seal. A dog owner whose dog attacks a seal could face prosecution. Anyone charged under the MMPA with harassing, disturbing, injuring or killing a seal faces a maximum penalty of two years' imprisonment or a fine to a maximum of $250,000.
