A 25-year-old man has appeared in court over an attack on Dutch tourists as they slept in their stationwagon on Thursday morning.

The man appeared in Invercargill District Court this morning charged with rape.

His name was suppressed and he was remanded in custody to appear again next week.

Police said he could face further charges at his next court appearance.

The tourists, a 25-year-old man and a 22-year-old woman, were staying at the Tuatapere camping ground, west of Invercargill.

At 6.40am, a man entered their car armed with a knife.

He raped the woman and stole a "large amount of cash", police said.

A second man whom police believe stood outside the vehicle during the attack had not yet been found.
