This is what happens when Taylor Swift walks into your restaurant.

After a barnstorming concert in Sydney on Saturday, the singer returned to New Zealand and made her way to the Captains Restaurant in Queenstown.

She was wearing a short black dress with flat black shoes, showing off her long legs, and was accompanied by a small party, including, it is believed, her mother Andrea.

The restaurant posted a picture of one its waiters looking shocked, accompanied by the caption: "OMG! TAYLOR SWIFT enjoying the scene at Captains tonight. Thank you Alex for looking after her and the crew."

Swift flew into New Zealand on a private jet at 8pm on Sunday and was taken in a convoy of three SUVs to accommodation in Queenstown.

At about 9.30pm, she was dropped off at the top of the town's mall and her party made their way to Captains Restaurant. They dined in a private area and did not attract public attention.

Swift played in Sydney at ANZ Stadium on Saturday night in front of 76,000 people, and her next gig is at Suncorp Stadium in Brisbane on Saturday.

It is understood she is in Queenstown to complete her new music video.

Swift reportedly arrived in New Zealand last Monday and was the subject of various sightings and more than one blurry picture in the following days.

She also angered Auckland conservationists who said her crew put a rare native bird at risk when filming her latest music video at a west coast beach near Auckland.

The local film production company behind the Bethells Beach music video has since apologised over concerns it disrupted nesting dotterel.

Swift's 1989 World Tour began in Japan in May and will finish with seven concerts in Australia.

New Zealand is not part of the 1989 tour. Swift last performed here in 2013.
