An investigation into a balcony fall in August which left a young woman seriously injured says the incident could have been the result of a "spontaneous failure" of a glass balustrade.
The glass balcony at the Quest Hotel on Ponsonby Rd shattered and resulted in the woman falling two storeys onto a rocky garden.
Owners of other apartments have been told to get professional advice and make "minor modifications" to reduce the risk of a similar incident.
Auckland Council investigated the balcony failure and found the glass balustrade complied with the building code.
