“Sadly, on emergency services arriving at the scene both occupants have been located deceased.”
A section of SH15 between Otaika and Maungatapere was closed and traffic was being detoured via SH1 and SH14.
The Serious Crash Unit had been advised and a scene examination would continue this morning.
“We continue to advise motorists travelling through this area to expect delays and to allow additional time to reach their destination safely,” police said.
The NZ Transport Agency earlier said SH15 was closed due to a serious crash just before 1am, with drivers advised to delay their journey or consider an alternative route.
Fire and Emergency northern shift manager Paul Radden confirmed Fenz had sent crews from Auckland and Whangārei to the accident but referred all further queries to police.
