They announced some demographic tracking testing a couple of weeks ago. When the number of infections is down they can start track and trace. Getting to that point probably requires most of the current restrictions, or at least the current level of infection control, to continue.
The smart thing to do if achievable would be to get more granular in progressively more ways, getting as much of the population as possible back to a modified normal by stages. Maybe the over 70s will have to stay bottled up for significantly longer, except for those with immunity if conferred by catching it.
