Telecom and nzherald.co.nz are giving one deserving business team of up to six people the chance to win a day sailing around Auckland Harbour.

Telecom staff were told this morning that the company's 'Mr XT', responsible for mobile devices and services, would leave at the end of his contract in July.

Telecom mobile phone customers on the network's XT and CDMA networks have experienced more intermittent outages today.

Some New Zealanders are likely to get a nasty shock while browsing the internet over the next few months - a web page on their computer saying "STOP!".

Telecom shares sank to new a low on the NZ sharemarket today, while rises in Fletcher Building, Contact Energy and other leaders helped carry the market higher.

New Zealand's government isn't trying to undermine Telecom by bolstering rural broadband services, Communications Minister Steven Joyce says.

Telecom's stock price hit an all-time low yesterday after it told the market that its share of the Government's new rural broadband initiative would cost it $168 million over three years.
