Television in Wairarapa will go digital on September 29.
Broadcasting Minister Craig Foss says lower North Island residents need to ensure they are ready for the digital switchover as research shows 20,000 households are not yet prepared for the deadline.
"Anyone who wants to keep watching television after the September 29 deadline needs to take a moment and check they are ready," he said.
You don't need a new TV to go digital but you may need some new equipment.
If you already watch TV on Freeview, Sky, Igloo or Vodafone, or if you are using a Freeview compatible device like a TiVo or PlayStation 3's Play TV you have already gone digital, so you won't need to change anything.
More than nine out of 10 households are already watching digital TV.
If you haven't already gone digital you may need a UHF aerial and set-top box or a satellite dish and satellite set-top box.
The equipment you need to watch Freeview digital TV is sold through retailers.
If you wish to watch Sky or Igloo, the company you choose will provide the equipment.
The cost of going digital will depend on your location and what equipment you need, but it's best to talk to your retailer or an installer about your options.
Instead of buying anything, you may choose to subscribe to a pay-TV service like Sky or Igloo.
Those companies will install the equipment you need to watch digital TV in return for a monthly fee.
Your local retailer can provide further information and advice.
