Grant McBeath has been appointed as interim CEO.
McBeath is currently the HMB customer channels general manager and has been at Spark for five years.
Paris has been the HMB CEO since July 2015, after he took over from Chris Quin.
Before his appointment, he was also with Spark New Zealand for four years as general manager for Spark HMB, and was with the company during the transformation from Telecom to Spark New Zealand.
