A 21-year-old-woman is in a critical condition after her speeding 22-year-old brother lost control of his car and smashed into a power pole near Havelock North.
Four passengers were in the car as the driver attempted to overtake another vehicle, lost control on a bend before it rolled and crashed into the concrete pole on Te Mata Mangateretere Road about 1.50am on Saturday.
A 20-year-old male suffered moderate injuries and was in a stable condition. The driver received minor injuries as did a 16-year-old female and 20-year-old male.
Sergeant Clint Adamson said it was not yet clear if the crashed vehicle was racing.
"Early thoughts were that they weren't racing per se but speed is definitely an issue - that might change in the next couple of days as we talk to a couple of more people who have come forward.
"Two weeks ago a young 18-year-old girl was killed. That one was definitely a race, but it wasn't a train [high-speed convoy] or anything like that."
"Now we have another young girl. I spoke to her family - she is very, very ill."
He said despite speed-related accidents, a large group of Bay boy racers, aged in their late-teens to early 20s, was not changing its behaviour.
Most vehicles had passengers
"There are members of the group that need to take ownership of what is going on - the so-called car enthusiasts that like to go out and have a good time. Within that group every weekend there are people doing stupid things.
"Generally they meet up in Napier once a week, usually Friday night, and then they go out on a so-called boy racer train of up to 50 cars."
Police were trying to determine how many cars were in convoy in the Havelock North crash.
"There were definitely more than just one or two cars - there were several there when we turned up."
Anyone with information who has not already been spoken to is asked to phone Hawke's Bay Police on 06 8730500 or the Crimestoppers Line on 0800555111.
