There's debate over the future of the country's nearly 2000 remaining phone booths.
Spark's planning to use the aging payphones for free calling, wifi, phone charging, and for digital advertising.
But Auckland Council wants a share of the return due to the booths being on public footpaths.
Spark Chief Brand Officer Leela Ashford told Heather du Plessis-Allan there are lots of little costs that go into running the booths.
She says it's all on Spark and their partner, and if they have to split revenue with councils and roading authorities, the business case falls over very quickly.
