She said she had met many people who thought they were receiving digital but were not.
"A good rule of thumb is to check you have a minimum of 13 channels. If you have, you don't need to do anything."
Ms Jones said a new television was not a necessity - most televisions only need a new set-top box. "You can shop around, as there is a big variety of prices for set-top boxes these days."
Set-top boxes can be installed by anyone, but a professional will be needed for a satellite dish or UHF aerial.
"If your television is receiving signal using bunny ears, for example, then you will need to get an aerial or dish installed," Ms Jones said.
People with SKY, Freeview or Igloo are already receiving digital, she said.
Going Digital had a presence at last weekend's technology expo, TechEx, in Wanganui.
"We were alongside other people and organisations talking technology, so it was a good platform for us to push our digital message," Ms Jones said.
Wanganui Chronicle reporter Merania Karauria is one of those who haven't yet made the digital switch.
After having the same 14-inch television for the past 20 years, her sister bought her a new television two years ago "because she thought I needed to upgrade".
Ms Karauria said she didn't know if the new television was receiving the digital signal, but thought it probably wasn't. "I can get the three main channels, but that's all. I think I have to get a Freeview box and I have to be connected to an aerial or satellite dish."
But Ms Karauria said she didn't watch a lot of television, so it wasn't her first priority.
"I'm not motivated at the moment to get something done about it. I have to get a new roof, and it all costs money."
