It has been a deadly night on New Zealand roads, with two fatal crashes occurring before midnight.
A series of smaller crashes have also seen people hospitalised with serious injuries throughout the country, police said.
One person died after a car plummeted off a one-way bridge into water in the Coromandel shortly before 10pm.
Police said emergency services rushed to the scene of the fatal crash on Purangi Rd, Whenuakite, in the Thames-Coromandel district about 9.46pm.
The car was seen to drive off the one-way bridge on Purangi Rd into the water.
