The clock has struck midnight - we are now in 2018.
New Year's celebrations have been ramping up through the night all around New Zealand.
Binge drinking is giving emergency services in Whangamata a busy night as dozens of teens require medical attention.
St John territory manager Lindsay Sattler said about 25 people had come to them for help in the Coromandel town tonight. They were all drug and alcohol related and most affected were under 18.
"We're very busy. It's stretching us."
Sattler said people were concerned their drinks had been spiked because they had become extremely intoxicated after only a few drinks. He said it was impossible to tell if drinks had been spiked without doing a blood test.
"Watch how you drink. Keep up the water and keep your drinks covered," was his advice.
New Zealanders are celebrating the end of 2017 at events around the country.
In Auckland, a mix of local reggae acts, including Sons of Zion, Three Houses Down, Hipstamatics, Sammy J & The Levites and DJ Karn Hall, are playing to fans at a block party at SkyCity in Federal St.
In Rotorua, the free Glo Festival, held at the Village Green, is hosting local entertainment, fireworks displays and headline act Elemeno P.
Those holidaying in the Coromandel are also keen to welcome the new year to some good music.
Buses are piling into Coroglen chocka with excited party goers.
