Spark is warning customers of a new scam doing the rounds.
The email purports to be from Spark and encourages people to pay their "bill".
"We are aware that there is a scam email circulating, impersonating Spark and requesting people to pay their outstanding balance on their Spark bill via a 'Pay Now' option," a Spark spokeswoman said.
"However, this is not a legitimate communication from Spark and we strongly encourage customers not to click on any links in the email and to delete it immediately."
The Herald received an example of the email from MySparkSupport@spark.co.nz.
