A 16-year-old boy is in a critical condition in Wellington Hospital after a single-vehicle crash in Whanganui on Wednesday morning.

The teenager was the only occupant of a car that hit a power pole on the corner of Anzac Parade and Rangitikei St. He was not wearing a seatbelt.

He was taken to Whanganui Hospital in critical condition and on Wednesday evening was transferred to Wellington Hospital. A spokesman said on Thursday afternoon the boy remained in a critical condition in ICU.

"It's a sobering reminder of the consequences of not buckling up," Central District Police road policing manager Inspector Brett Calkin said.


"It takes just a couple of seconds, yet it drastically reduces your chances of serious injury in a crash."

The Serious Crash Unit is investigating.
