Carisbrook Heights School in Dunedin will close for good at the end of the year.

The school's board of trustees made the decision based on decreasing student numbers.

All classes will be transferred to the main site Carisbrook School in South Road.

Carisbrook Heights was formed as a result of a merger in 2011 between Caversham, College Street and Calton Hill Schools.

Enrolments have halved since it opened in 2012 and now stand at 29.
