If you're still not on fibre, you may have noticed an aggressive new strategy by Spark and Vodafone.

Both companies are trying to cut Chorus' lunch by getting customers who aren't on fibre on wireless broadband instead of their normal ADSL or VDSL connection.

Jarden head of research Arie Dekker told Heather du Plessis-Allan that both companies want to provide a broadband service that exists on their current plans. 

"The benefits for Spark is that they can price the product at reasonably similar levels to copper or fibre broadbands but cut out Chorus."

He says they have around 150,000 customers on their plan, which saves them tens of millions a year. 

However, Dekker says that there is enough space for them all to exist - as Chorus has over 1 million customers.
