Tuakau College students have gone home for the day because of a power cut.
Assistant principal Ally Fletcher said about 400 students in Years 7 to 10 were sent home late morning after a trailer came off the back of a ute in Buckland Rd and hit a pole supplying power to the college just after 9am.
The Ministry of Education advised that schools should be closed if power was expected to stay off for more than two hours.
"We were advised that it was going to take at least a day," she said. "We were told just before we left at lunchtime that they expected it to be up and running tomorrow."
She said exams for the National Certificate of Educational Achievement (NCEA) went ahead for senior students as planned.
