The death of the landline may be imminent.
Research carried out by Canstar Blue, which rates products for consumers, has found a third of Generation Y don't have landlines.
Instead they opt to use their mobile phones to make their calls.
Just over half of Kiwis and two thirds of Generation Y are choosing for the pay-as-you-go option.
Gen Y are also four times more likely to spend their employer's time to check social media updates on their mobile phones than older colleagues.
