It expects to save $100 million to $120 million a year in payroll costs as a result of this.
Telecom is reviewing its business and making changes in an effort to build "a leaner, more agile organisation" and get its costs to a point where it can remain competitive.
The company said it today it expects adjusted ebitda (earnings before interest, tax, depreciation and amortisation) to remain $1.04 billion to $1.06 billion for the 2013 financial year, which ends 30 June. Management expects ebitda to be at the bottom this range, because of price competition in the fixed-line market and "margin pressure" in its information technology arm, Gen-i.
Telecom said its guidance for capital expenditure to stay around $460 million for this financial year.
Over the next three financial years, Telecom expects to invest $400 million to $500 million a year as it "executes its new strategy".
Telecom chief exectutive Simon Moutter is holding a briefing for investors and analysts today on the company's new strategy.
"The strategy outlines the steps Telecom is taking in New Zealand to shift from a traditional fixed and mobile infrastructure company to a future-oriented, competitive provider of communication, entertainment and IT services delivered over its networks and the Cloud," the company said today.
