Although the mayoral taskforce reports improved behaviour since July with greater monitoring of licensed premises and stronger enforcement presence, Auckland Central Police asked for bans to cover the Wynyard and Victoria quarters to the west of Viaduct Harbour.

Victoria Park was used by some groups for drinking and was close to entertainment premises.

Temporary bans for the Rugby World Cup gave police a tool to deal with preloading and a thousand warnings were given in each October and November. The numbers went down to 200 in March but rose to 700 in August.
Since the cup, the council has reviewed the existing central city liquor ban area, which includes all streets and public places, council car parks and a night-only ban on Victoria Park. The review recommended extending the ban to the historic Symonds St Cemetery, including Pigeon Park.
Since the last council extension of the all hours ban in 2004, the cemetery and Victoria Park have become popular drinking areas for rough sleepers and homeless people who were barred from spots nearer the city centre.
