A baby humpback whale was spotted cruising near the entrance to Tauranga Harbour, yesterday.
It was spotted about 8.30am yesterday by those on board the Dolphin Seafaris cruise.
Crew member Sam Gilbert said at first those on board the boat thought it was a shark.
"Its tail popped out and holy crap it was a humpback," she told the Bay of Plenty Times.
Those on board the boat had the pleasure of seeing the marine mammal breach and swim near the boat for about half an hour.
