Analogue televisions in the South Island will show nothing but static today after a switch to digital overnight.
A Go Digital spokeswoman said about 98 per cent of South Island households which had televisions had already made the switch, so were not affected when the change occurred at 2am today.
The digital switch-over occurred for Hawkes Bay and the South Island's West Coast in September last year, the rest of the South Island switched this morning, and the rest of the North Island will make the change in stages later this year.
Most of the country had already converted to digital television, with about nine out of 10 households in Auckland having made the change, the spokeswoman said.
Previous concerns that installers would be unable to deal with the backlog of people wanting to install digital television had abated, and there did not appear to be any outstanding issues.
