Extra police officers are being sent to Auckland from other parts of the country during the final stages of the Rugby World Cup.
More than 100 police officers from the South Island and other parts of the North Island will be seconded to Auckland for the remainder of the tournament.
Police Assistant Commissioner Allan Boreham says the presence of the extra staff is a contingency to cope with increased numbers at fan zones.
Auckland Council last week established fan zones at Albany, Henderson and Mangere to take pressure off the waterfront party area.
The council's chief executive, Doug McKay, says 14,000 people gathered at the newly-opened zones on Saturday.
Mr McKay says while each costs $100,000 - $130,000 per day to run, they give people a choice of where to celebrate in coming weeks.
