"What we do know without sugar-coating this is that it is apparent it will be a number well into the hundreds. I can't be more specific than that right now but we will be a in a position to share more information over the next two to three months."
Moutter said there was no area of the business that had not been asked to "look hard at everything we do to make sure we remove the legacy culture - layers of middle management, the duplication of effort and find a way to make a contribution to get our cost base more competitive".
During a conference call this morning, Moutter said that Telecom's cost-base "unfortunately remains uncompetitive".
He said Telecom had a higher cost-base and that the company employed more people than similar companies in the telco and ICT sector.
Moutter said there was no point waiting to implement changes until the next financial year:
"We believe we must move quickly," he said.
The Herald understands a range of options are being considered, including compulsory redundancies and non-replacement of departing staff.
Telecom, which employs around 7000 people, also this morning reported adjusted earnings before interest tax, depreciation and amortisation of $506 million for the half year period, up 3.7 per cent from the six months to December 2011.
Its adjusted first-half revenue of $2.1 billion was down 8.5 per cent on adjusted revenue from the same period the year before. It is paying an interim dividend of 8 cents per share.
In a statement, Telecom chairman Mark Verbiest said the company had begun a strategic shift from being a fixed-line and mobile player to a "competitive, future-orientated mobile and data-centric service provider".
"Behind the headline numbers, our business is changing significantly. Mobile revenue is higher on the back of demand growth and there has been good growth in net customer connections since the closure of the CDMA network. On the other hand, fixed calling revenue has continued to decline in line with industry trends and following a strategic decision by our Australian unit AAPT to rationalise some low margin business. These revenue shifts reflect the major global trends as the telecommunications sector is becoming increasingly focused on mobile and data," Verbiest said.
The company is due to give a more indepth update on its strategy in May.
Telecom chief executive Simon Moutter said it had added 103,000 mobile customers since August - after it closed the older CDMA network last year. That would put the total number of Telecom mobile connections at around 1.7 million.
After announcing the company hoped to stabilise its slipping market share in broadband last year, Moutter said today that Telecom had gained 13,000 customers in this area in the six months to December.
He called this "a good performance in the context of an intensively competitive marketplace".
Telecom has around a 50 per cent share of the broadband market.
