"If competition is real, then Chorus faces the prospect of having to use price to protect against penetration loss. Fibre has advantages but fixed wireless will look to compete on convenience and Spark will target customers at the lower end of the usage curve."
Spark has clawed back more than $60 million a year in revenue over the last couple of years from Chorus through selling wireless broadband but the limitations of the 4G technology mean it probably won't gain too many new customers for this offering.

However, Spark is champing at the bit to get 5G technology with its greater bandwith up and running and that should increase its addressable market for wireless broadband.
Dekker says the 5G technology does provide Spark with an opportunity.
"5G will unleash further potential in wireless networks and it is worth bearing in mind the incentives on mobile network operators without fixed network assets to look to compete in broadband," he says.
"To date, only Spark has used fixed wireless in a meaningful way to bypass copper inputs. In time, we expect lower usage fibre users to be targeted and the switch-off of the copper network will also provide Spark and other mobile network operators with an opportunity to target fixed wireless as a broadband alternative."
Chorus was spun out of Telecom in 2011 by government fiat ahead of the UFB rollout and Telecom changed its name to Spark in 2014.
No date for turning off Chorus' legacy copper network has been set and it will need parliament to pass enabling legislation but it is expected to be turned off in stages.
The competition regulator, the Commerce Commission, has already started a three-year process to implement the new regulatory framework for fibre pricing to take effect from the start of 2022.
Dekker says the new regulatory regime will be similar to the regime used for power companies and airports, one that investors are used to "and have some confidence in."
Nevertheless, investors need to keep in mind that the telco regime will have some differences.
