Spark New Zealand head of home, mobile and business Chris Quin, a 20-year veteran of the company and one-time contender for the top job, will leave the telecommunications company at the end of June this year.
Quin has had numerous roles with the company, including acting as chief executive, and has been in charge of the home, mobile and business unit, which accounts for almost half of the group's revenue, since Simon Moutter re-joined the company and took over the reins in 2012.
Quin will be replaced by Jason Paris, who is currently the company's general manager of home, mobile and business.
Paris joined Spark in 2011, having been in charge of television at MediaWorks' TV3 and previously running Television New Zealand's digital media strategy.
"By any measure, Chris has done a consistently terrific job in a range of executive roles at Spark New Zealand and Telecom/Gen-i before that," Moutter said in a statement.
