Plant thefts at Christchurch's Mona Vale caught on CCTV

There's been a string of brazen plant thefts from the Mona Vale Garden Park over the past 6 months, with some flowers and bushes literally disappearing overnight. The Historic Mona Vale homestead is surrounded by more than 5 hectares of stunning grounds, including manicured lawns, mature trees and flower gardens; beautifully kept by staff and an army of volunteers. A number of the garden raids have been caught on CCTV, but help is needed to identify the theives. Susan Lawrence speaks to Lisa Owen.
