Hardware, pet stores, agricultural and office supply stores will now be required to operate using only click and collect or delivery-only options as part of new Covid restrictions.
But smaller businesses will be able to allow some people back into workplaces, in certain circumstances.
It comes after 19,000 people checked into a Bunnings stores across the ACT in one day in Canberra during the lockdown.
The new restrictions will come into effect from 11.59pm on Friday, after being announced by Chief Minister Andrew Barr during his daily Covid update.

Businesses that have 20 or fewer full time equivalent workers will be allowed to operate under the new restrictions.
The new restrictions also include gyms, health clubs, fitness centres and dance studios to have two people inside the facility to film, live stream or broadcast fitness classes.

However, house inspections and auctions are still not allowed to take place in person and must be done online.
