Police Commissioner Mick Fuller has "personally reviewed" and cancelled 32 of almost 1000 infringement notices issued across the state since the public health provisions came into effect four weeks ago, with lawyers warning that many more may be annulled by the courts.

Since the public health order on March 31 to compel people in NSW to stay in their homes unless they have a "reasonable excuse", fines have been given to 991 people including a 17-year-old boy who said he was "bored" and visited a friend, a man who claimed driving was a form of exercise before allegedly telling the issuing officer "this $1000 fine won't hurt with my $15 million" and a man who allegedly told police he was out of the home to buy drugs.

In most cases, individuals are issued a $1000 fine, while businesses receive a $5000 infringement notice.

Police say the review process is ongoing, and the commissioner has not yet assessed every fine but continues to work through them. At this stage, the 32 fines dismissed represent 3 per cent of the total.
