From 12 January, you must report a positive rapid antigen test result.
"This health order has been signed off this morning," Premier Dominic Perrottet told reporters on Wednesday.
If someone fails to register a positive RAT there will be a $1,000 fine, which will be enforced from 19 January, he said.
While all positive RATs since 1 January can now be reported, the mandate only applies to positive tests from Wednesday.
Mr Perrottet said the reporting process would "only take a couple of minutes".
All states and territories aside from the ACT and Western Australia have now provided a way for residents to register their results from RATs.
You can register a positive test result for yourself, another adult or a child. Each result needs to be reported separately.
You should register your positive test result as soon as possible by visiting the Service NSW app or website.
