"We also have two amazing motoring museums; Transport World and Motorcycle Mecca, not to mention the fantastic southern food served here from some award winning cafes," Graber told Fairfax.
"If budget constraints were a consideration there are plenty of awesome attractions which cost nothing: Southland Museum & Art Gallery offers the opportunity to see tuatara, and it's on the edge of Queens Park, where there are stunning winter gardens and the aviary.

"I said to Stu 'What the F is this?' I actually burst into tears because I'd been looking forward to it since June. Then we got to the accommodation and, looking it from the outside; I said 'oh my God'," Rowling told Fairfax.

Air New Zealand had since offered a full refund for the trip.
Anna Cross, the external communications consultant for the airline, said: "We're really sorry this Mystery Break didn't meet the customer's expectations and have offered a full refund as a gesture of goodwill."
