I live in NZ, and after a recent exposure to Covid, I experienced said daily check in calls from the government that really relied on trust (honesty) more than anything, as far as I’m aware — I suppose it’s possible they were tracking my phone in some way to ensure my location stayed contained/consistent? Seems highly unlikely though.

I will add that if I’d been caught leaving the house, outside of a short daily workout, I’d have been liable for a fine and/or jail time.
