Mark Petrie is 2degrees' chief fixed officer and the owner Snap, a Christchurch-based broadband provider 2degrees.
2degrees acquired Snap in 2015 before launching its fixed-mobile services in a move to become a full-service communications provider.
The telecommunications company has announced that Petrie will leave the company later this year.
When the 2degrees and snap came together under the 2degrees umbrella, Petrie moved in to the role of chief enterprises officer at 2degrees before his position as chief fixed officer.
Petrie also became a 2degrees shareholder as a part of the deal.
Petrie says that while he's stepping out of the day-to-day role he will be an ongoing shareholder with a strong interest in seeing 2degrees further succeed.
"I really could not have chosen a better partner for Snap - which has made working in 2degrees for the past couple of years a lot of fun," says Petrie.
"Now that the biggest part of the integration between the two companies is complete, I can step away from the operational side of the business, while maintaining an interest through my shareholding.
"I'm keen to do some different things and feel assured 2degrees has a strong market position, with plenty of capable people in the business that can carry things on without me.
2degrees CEO Stewart Sherriff says Petrie brought more than just Snap to 2degrees, staying on to make sure the integration went smoothly and to ensure both organisations could combine to become the country's fastest growing telco.
"Mark put personal effort into making sure 2degrees could deliver on the promise of being a full-service telco for all market segments," adds Sherriff.
"He's been at the forefront of continued growth in broadband and new business with major organisations.
Sherriff says Petrie will be with 2degrees until late September.
