Queenstown Lakes District Council spokesman Jack Barlow said the council had been working with Chorus, Spark and Vodafone on plans to relocate and install new services ducting along the length of the upgraded road.
"This will facilitate future upgrades to the network and avoid works to the upgraded road at a later date," Mr Barlow said.
Ballantyne Rd was closed to through traffic, but access to properties remained open for residents and essential services.
The $6.4 million upgrade, jointly funded by the NZ Transport Agency, was programmed to take six months to complete, he said.
