A seal was found paddling about in Karamu Stream in Havelock North, much to the delight of onlookers.
"Although seals are marine mammals, they spend a lot of time on land and can sometimes show up in places you might not expect, occasionally following rivers upstream," a Department of Conservation spokesperson said.
It's far from unheard of, with adolescent seals often popping up inland between about July and September.

They can appear up to 15km inland in unusual places, such as a paddock, as with one seal found at a rural property in Twyford, Hastings in February this year.
