The Department of Basic Education says a special task team was set up to probe how the leak occurred and also the scope of it.
The Department says the task team had briefed Basic Education Minister Angie Motshekga on the impact of the leak.
Department spokesperson, Elijah Mhlanga, said it had resolved that learners from the Vhembe district would re-write Life Sciences Paper One and Paper Two.
He says this decision was taken after it was confirmed that a copy of the 2015 National Senior Certificate examination paper for Life Sciences was circulated amongst some learners before the commencement of the examination.
