A man critically injured in a single-vehicle collision near Ohaupo, Waikato late last month has died in Waikato Hospital.
Dominic Frances Smith, 23, suffered severe injuries in the August 29 crash.
"This is a tragedy for both his family and the medical staff at Waikato Hospital who endeavoured to save him,'' said Waikato road policing manager Inspector Leo Tooman.
Mr Tooman said the death, the 28th on Waikato roads this year, is a reminder to people that rural roads in the region have to be treated with caution and respect.
"It all comes down to driving at the appropriate speed for the environment and making sure that belt is fastened.''
