There are calls for a national bed register, to stop so called ghost communities caused by short term holiday rentals. A bed register could force operators, like AirBnB, to share data with local councils; including accommodation addresses. The concern is that some areas, particularly in visitor hotspots, are being taken over with temporary accommodation... hollowing out neighbourhoods and making it hard for residents to find accommodation. Christchurch councillor Nathanial Herz Jardine spoke to Lisa Owen.
