A man died after the car he was in was washed 100m down a flooded creek during heavy downpours in Northland.
It was one of six fatal car accidents over the weekend in a deadly start to the school holidays. Several people were also seriously injured.
The incident, in Omanaia, west of Kaikohe, happened just before 10pm on Saturday.
Two men aged in their 50s were leaving a house on State Highway 12 when they went to cross a ford which usually allowed access across a creek between the house and road.
Serious crash investigator Senior Constable Warren Bunn said that as the men went to cross the ford, their van was swept more than 100 metres downstream.
The driver managed to escape the vehicle with minor injuries. The passenger, from Omanaia, was found dead on the bank a short way from the van.
"The ford itself is easily passable but with the heavy rain, the van has entered it and been swept away," Bunn said.
Volunteer fire crews from Rawene were also at the scene with the station's chief fire officer Dave Williams describing the downstream current as "pretty fierce" following heavy rain.
Williams said about 15 members of the man's family scoured the banks of the swollen waterway in driving rain and pitch darkness desperately trying to find him.
He was eventually found by one of the Rawene brigade's most experienced officers two hours later as he returned to parts of the stream that had previously been searched after noticing a slight kink in the water.
A rescue was mounted at midnight with the firefighter tied with ropes and held fast by emergency workers as he entered the raging torrent to pull the man free from under a branch.
Williams said family were relieved their loved one was found so quickly allaying fears he had been swept into the harbour.
The driver was distraught about what had happened, he said.
Williams said he knew the deceased, "a really really nice guy". "We're a small community, so [knowing the victim] is something we deal with regularly," Williams said.
The man was now being to the Mahuri Marae for a tangi.
Bunn said it was not yet clear whether the death would be classed as a fatal car crash or a drowning. If it was included as a fatality it would take the region's toll to 24. This compared with 2015's 23 road deaths in the region.
In another crash in Northland, a 19-year-old man died at the scene after a vehicle he was a passenger in left State Highway 1 and hit a tree, near Towai just after midnight yesterday.
The ute was driven by a 21-year-old who lost control of the southbound vehicle as it rounded a corner, Bunn said.
The ute hit a tree and ricocheted about five metres down a bank, landing on its roof. The driver was able to free himself and flag down a passing car, Bunn said.
He was transported to Kawakawa Hospital in a serious condition.
Kaumatua have blessed the sites of both crashes, and the Serious Crash Unit continues to investigate the cause of each incident.
Northland Duty Inspector Riki Whiu said: "Our condolences and thoughts go out to the local families of those who have died in these tragic incidents.
"Any death on our roads is a tragedy, and it's especially difficult for all of our staff to have two fatal crashes in the space of one night.
"Police wish to remind those travelling on our roads, in particular in such terrible driving conditions, to drive to the conditions and look after each other."
Both crashed have been referred to the coroner and next-of-kin are being notified.
Fatal crash closes main road
Yesterday afternoon, the male driver of a car, aged in his 40s died after a serious crash near Warkworth, which closed State Highway 1 in both directions.
The person was trapped for 40 minutes in a vehicle after the incident, 5km south of Warkworth.
He died en route to hospital.
SH1 was closed between Woodcocks Rd and Puhoi Rd. The road was also closed at Silverdale but diversions are in place.
Emergency services were called to the scene just after 3pm, where a southbound vehicle and a northbound vehicle collided, according to Waitemata Police.
Another person was seriously injured and two others were moderately injured.
Police chase ends in death
A motorcyclist died early Sunday morning trying to flee from the police in a chase.
The driver refused to stop for police when the bike was seen travelling at speed about 1.15am in Mt Albert.
The motorcyclist failed to take the Royal Oak roundabout and fell off the bike, hitting a parked car.
Police are investigating and the Independent Police Conduct Authority has been advised.
And south of Waiouru on SH1, one person died after a crash yesterday morning.
The single vehicle crash happened just before 5.45am about half a kilometre south of Springs Hill.
And a man died after the car he was driving hit a power pole in Taranaki on Ketemarae Road, Hawera on Saturday about 4.15pm.
The male driver was the sole occupant of the vehicle.
National manager road policing Superintendent Steve Greally said any death or injury on the roads was "one too many".
"Everyone - including road users - need to do their part to reduce deaths and injuries on our roads and in our communities right across NZ.
"Police cannot do it alone. Road safety is everyone's responsibility.
"Education and Police enforcement is just one aspect of keeping the roads safe. The driver and the decisions they make are also an important part of the picture.
"Making smart decisions on the road can be done by following the basic road safety rules."
He reminded drivers to check their speed, drive to the conditions, avoid alcohol, take rest breaks and always wear seatbelts.
He said: "Not all roads are created equal - many of New Zealand's roads are unforgiving and leave no room for mistakes.
"Many of our rural roads are not five star roads and our bodies are fragile. The speed limit is the maximum speed you can travel at safely in ideal conditions. Often a strip of paint is all that separates you from oncoming traffic.
"If you crash - regardless of the cause or who is at fault - speed is the single factor that most affects the outcome. Just a few kilometres per hour can be the difference between avoiding a collision - or a crash with a tragic outcome."
