Three Boston University students who were studying in New Zealand were killed Saturday when their minivan crashed. At least five other students from the university were injured in the accident, including one who was in critical condition.

The students were traveling in a minivan at about 7:30 a.m. Saturday near the North Island vacation town of Taupo when the vehicle drifted to the side of the road and then rolled when the driver tried to correct course, New Zealand police said.

Three of the students died at the scene, police said. Another woman was in critical condition at an area hospital, while at least four other students suffered moderate injuries.

Boston University spokesman Colin Riley said the deceased students were Daniela Lekhno, 20, of Manalapan, N.J.; Roch Jauberty, 21, whose parents live in Paris; and Austin Brashears, 21, of Huntington Beach, Calif. New Zealand police confirmed their identities.

Another BU student, Margaret Theriault, was airlifted from the crash site to a hospital in Taupo and was in critical condition, the university said.
