Taylor Swift's brother Austin and mother Andrea joined the US singing superstar in Queenstown yesterday.

The pair are in the resort with the 25-year-old Grammy winner and were seen enjoying the sunshine and shopping in the CBD, stopping in at Partridge Jewellers, Kathmandu, Mikael New Zealand and 45 South before being whisked away.

Swift arrived in Queenstown on a private jet just after 8pm on Sunday, fresh from her concert in Sydney, part of her 1989 World Tour.

She and her family walked undetected through the town's busy mall an hour and a half later and dined privately at Captain's Restaurant.

Grant and Karen Hattaway - seated outside the restaurant celebrating their last night as owners - said they did a double take as Swift swept past, with security stationed outside the premises and at other points in the CBD.

It's the second time in less than a week Swift has been in the resort, having arrived last Wednesday and leaving on Friday. During that time it's understood she filmed part of her new music video for Out of the Woods.

Swift had earlier last week also been filming at Bethells Beach in northwest Auckland where her film crew allegedly endangered nesting dotterels, a rare native species.

The local film company behind that video, Cherokee Films, has since apologised but disputed any dotterels were harmed and offered to make a donation to the breeding programme.
