A new pipe will be installed in Queenstown Mall on Monday, the Queenstown Lakes District Council has confirmed.
The pipe will fix the water main that burst earlier this week.
Contractors Veolia will prepare the site over the weekend, before installing the pipe.
The work should be finished within a week.
Veolia will also install a rider main to provide additional resilience and security of future supply, council communications and engagement manager Naell Crosby-Roe said.
Contractors Downer will repair the pavement once the water main repairs are completed.
This will include re-levelling the underlying surface and re-laying the cobblestones.
Downer would stage the work to provide safe, continued access to all businesses in the lower mall, Crosby-Roe said
That work was expected to take two weeks.
With the exception of a brief late night or early morning shutdown to activate the new water main, no disruption to the area's water supply was anticipated during the work, he said.
The council will advise business owners of the details of any shutdowns.
