Increasing popularity of naked broadband - supplied without the need for a landline - is contributing to the demise of the traditional fixed phone line in New Zealand households.
Vodafone says 40 per cent of its new broadband customers opt not to have a fixed landline.
The move to hang up traditional landlines has also been borne out by research firm International Data Corporation (IDC), which notes the number of nationwide fixed line connections has dropped at a rate of about 1.4 per cent a year over recent years, from 1,314,000 in 2007 to 1,258,000 now.
It is a trend that is being seen worldwide - New Zealand's drop of 8 per cent in landline connections between 2007 and 2011 is less than Western Europe's 16 per cent.
But Shane Minogue, of IDC, said he expected New Zealanders to give up their fixed lines at a faster rate in future with the introduction of fibre technology.
