Police Commissioner Stephen Caldwell said it was a difficult time, but police needed the public to follow instructions and comply with directions.
"People need to stay home during the curfew hours," he said.
Since the curfew started police said there had been a 37 percent drop in reported crime, compared with last year.
Police are working with Tonga's military and the Fire and Emergency Services to enforce the curfew.
