A Carterton man has been told his mail can no longer be delivered to his home - because there is no such address.
Russ Sadler's property number changed last year from number 15 to 21, as a result of a switch to the RAPID (Rural Address Property Identification) system, which is used to assist emergency services locate properties.
Properties are numbered based on the distance they are from the start of the road - in Mr Sadler's case, because his property is 210 metres from the road junction, it is number 21.
He said he has no issue with the system, but does have a problem with New Zealand Post's response to the change.
In a letter sent to Mr Sadler last month, NZ Post said after giving him a period of grace, they could no longer deliver mail addressed to number 15, only to 21, even though he lives in the same house.
