Hundreds of people were arrested and charged with alcohol-related offences over the weekend during a trans-Tasman police operation.
The joint initiative, Operation Unite, was conducted on Friday and yesterday and was a collaboration of Police Commissioners across Australia and New Zealand.
Police said the intention of the operation was to highlight the implications associated with alcohol misuse in public, including crime and anti-social behaviour, and health and injury problems.
A spokeswoman said more than 700 New Zealand police staff took part in Operation Unite on Friday night and more than 800 were involved last night.
Police checked licensed premises and party venues, carried out foot patrols, and had compulsory breath testing checkpoints.
