It seems “our” orca are still hanging around in Tasman Bay. From the Nelson Mail today:
“A pod of orca has turned on a special welcome for walkers heading into Abel Tasman National Park, and for sightseers at Mapua. “
They like eating stingray, apparently, and there are lots in the bay. NZ orca are the only ones in the world known to fancy a snack of ray. I hope they’re still around when I get back to the Abel Tasman in late February. I should be able to see stingrays, but the orca will almost certainly have moved on.
