Her first two New Zealand shows were instant sell-outs, so Taylor Swift has announced it will be third time lucky for many of her Kiwi fans.

The four-time Grammy winner is hot property, with shows scheduled for March 16 and 17 selling out at a lightning pace. A third show was today confirmed for March 18.

Described as a two-hour theatrical production, the Speak Now world tour features costume changes, dancers, aerialists and innovative choreography.

And Swift will be joined on stage by four-piece Nashville band Hot Chelle Rae, who have sold a whopping 1.6 million digital downloads in the States.
