An international freeze on Libyan assets has affected the scholarships of Libyan students studying in New Zealand.
The University of Auckland says funding needs to be found urgently for students whose payments were stopped on Thursday.
The six Libyans are in the country thanks to an agreement signed by the Libyan and New Zealand governments in October last year.
Four are at the University of Auckland, which is using emergency funds to cover their living costs until a longer term source of funding is agreed with the New Zealand Government.
Education New Zealand says the two other students are in Christchurch.
The university says the Libyan embassy in Australia has said it will repay the money when it can.
The problem has also affected hundreds of Libyan students in Australia, with the government reportedly loaning the Libyan embassy $1.9 million to cover the students' living costs.
