If you're thinking about sending a get well soon card to a loved one in hospital - you might need to think again about how you do it.
The Postal Workers' Union says posties have been instructed by NZ Post that letters and cards addressed to the street address of hospitals must be returned to the sender.
It's part of a new return to sender policy applying to businesses and institutions.
Kathryn speaks with Postal Workers Union Co-National President, John Maynard.
NZ Post says most big businesses, government agencies, shops etc have both a physical address and a postal address - usually a PO box where their mail gets sent. It says mail is still being delivered, so long as it is correctly addressed.
