Analogue televisions in Hawkes Bay and the West Coast will only show static this morning after the regions switched to digital overnight.
About 96 per cent of homes from Norsewood to Tutira in Hawkes Bay, and the South Island's West Coast from Haast to Karamea were prepared for the change overnight.
The rest of the country will officially go digital in stages from April next year, with the upper North Island the last to make the switch on December 1 2013.
Digital TV promises better picture and sound quality, more channels, and other features such as on-screen TV guides.
Eighty-six per cent of New Zealanders have already converted to digital television - an increase of two per cent compared with the previous quarter.
