An Invercargill school has changed its roll-checking procedures after a schoolboy was allegedly abducted by his stepfather.
Mike Zhao-Beckenridge, 11, was picked up during the March 13 lunch break from James Hargest College's junior school in Invercargill by his stepfather, John Beckenridge, in breach of a parenting order.
More than a week after they disappeared in Southland Mr Beckenridge's car was found at the bottom of an 88m cliff near Curio Bay.
Their bodies have not been found.
Yesterday, college principal Andrew Wood said the case had traumatised staff members and led to a change in the way students were monitored.
