Arch rivals Telecom and Vodafone have joined forces to try to deliver high-speed broadband to more NZ homes and schools.

Vodafone New Zealand are down 35,000 customers in the quarter ending September according to reports from its UK parent.

Kiwis who make only a few calls from their home line a month are paying the highest line rental in the OECD, says the Commerce Commission.

Telecom shows its reluctance to give up monopoly.

Telecom reported a 36.8 per cent fall in first quarter net earnings to $103 million, with underlying earnings hit by higher regulatory costs and intensifying competition.

NZ's largest corporate relocation has begun as Telecom shifts 2650 staff into its new $280 million international HQ in Auckland.

The Singapore stock exchange takeover of its Australian counterpart is "good for Australia, bad for us," says an adviser to John Key.
