Vodafone, Telecom, 2degrees and Telecom have joined with Paymark to launch a 'mobile wallet' joint venture.

The Warehouse seems to have fallen out of favour with consumers this week but maybe not investors.

Those at the helm of Telecom's youth-focused mobile brand "Skinny" say they have no plans to align its image with that of its "reliable" parent.

A slimmed down Telecom said its demerger-adjusted net profit came to $240 million in the first half to December 31, up 51 per cent.
