Colmar Brunton methodology shifts to reflect young voters without landlines

Polling company Colmar Brunton has shifted to mix of landline and mobile calls.

The new polling methodology is designed to give a more accurate result, according to Jason Shoebridge, CEO of Colmar Brunton's parent company Kantar Insight New Zealand.

The methodology is a mix of 50 per cent landlines and 50 per cent mobile calls. 

Mr Shoebridge said 20 per cent of 18 to 34-year-olds do not have a landline to call and the number is expected to increase. 

"It's about future-proofing our polls."

He said this method is "a better way to go," instead of online. 

"Not speaking to someone potentially gives a disconitunity in the trend."
