Stranded: TVNZ presenter Sam Wallace doesn't know where he is

Sam Wallace wasn't having much luck on Great Barrier Island.

Sam Wallace had a bad day yesterday, with the TVNZ weather presenter messing up his location not once but twice during a live broadcast.

The Breakfast presenter on TV One was visiting Great Barrier Island when he confused it with Waiheke Island during an interview.

"I'm sorry, I've just put my foot in it, I do this occasionally," he said after being corrected by his interview subject.

He repeated his mistake later on during the same interview, asking his subject, "how much does a flight to Waiheke Island cost?".

"I've done it again!" the frustrated presenter exclaimed.

Wallace made the mistake not once but twice.

"I'll tell you one way to annoy everyone on Great Barrier Island and that's to keep calling it Waiheke Island ... I keep ruining everything."

To make matters worse, Wallace later tweeted that he'd been unable to get off the island because bad weather had grounded flights.
