The country's last analogue television transmitter has been switched off.
The analogue signal for properties in the upper North Island was turned off at 2am on Sunday by Broadcasting Minister Craig Foss at the Waiatarua TV tower in Auckland's Waitakere Ranges.
Television can now be viewed only on the digital signal throughout the country.
Mr Foss said says it was an historic moment and the most significant change to television broadcasting since colour was introduced in 1974.
He says about 94% of New Zealanders have already made the switch from analogue to digital.
Mr Foss said that, by last week, there were 49,000 households in the upper North Island still to go digital.
