Mobile brand 2Degrees has called a media briefing today to "announce a major development regarding the future of the business."
2Degrees declined to offer any more detail but some industry sources have predicted a reappraisal of its ownership structure.
It is not clear if that would relate to a new investor or consolidation by one existing shareholder.
The company also expected to reveal a new broadband offering that would help it to compete with packages from Spark and Vodafone.
2degrees began in 2009 and broke the duopoly of Telecom and Vodafone.
In January three directors resigned from Communications Venture Partners (CVP) - a European based investment company with a 27 per cent stake in 2degrees - amid questions about its ability for growth.
