A number of Napier Girls' High School students excitedly sat in beauty salons as hairdressers and beauticians began to prepare them for their big night.
Their beautiful satin dresses hanging from their bedroom doors at home as they prepared for their biggest annual event - the school ball.
Excitement turned to disappointment and sorrow as the school announced an abrupt cancellation on Friday night, due to "health and safety concerns".
The school has made no decisions on whether the ball will be re-scheduled and would not comment any further on the subject.
Eastern Police also said there had been no updates of any note and the investigation into the threat was continuing.
