One of the country's longest running email services is about to start charging customers.
Spark is introducing a charge for Xtra mail from the middle of May.
The company says its costs to run the service have increased significantly and it's no longer sustainable to offer it for free.
It will soon cost almost $6 a month for Spark customers, and nearly $10 a month for everyone else.
Spark Product Director Tessa Tierney speaks to Lisa Owen.
