Young people, particularly girls, drinking excessively and putting themselves at risk are concerning police.

Liquor bans are in place and police numbers are being boosted in many of the traditional New Year's Eve hot spots.

Police have told parents to keep track of their children after finding a girl, 14, having allegedly drug-fuelled sex near a beach overnight.

A large slip overnight has blocked State Highway 25, just south of Whangamata, on the Coromandel Peninsula.

The Coromandel is promising cheap RWC accommodation rates that will undercut Auckland packages reaching into the thousands.

Revellers celebrating New Year and the start of a new decade in New Zealand behaved themselves last night.

The policing of a liquor ban in Whangamata has come under fire from holidaymakers who say the zero-tolerance approach is too heavy-handed and lacks common sense.
