Police search and rescue crews will carry out another mission to find a Taranaki man missing for more than a year.
Karl Roberts hasn't been seen since crashing his car on Uruti Rd on August 1, last year.
Police, LandSAR, family and friends carried out exhaustive searches for the 31-year-old but his disappearance continues to remain a mystery.
This weekend a search and rescue exercise will be held in the Uruti area, about 30 minutes north of New Plymouth, to search for Roberts.
Constable Andrew Wong Too, Officer in Charge of Taranaki Search and Rescue, said they would be joined by crews from Whanganui Police SAR and LandSAR from as far afield as Whanganui, Taihape and Ruapehu for the two-day search.
"Our dedicated and experienced SAR people are committed to doing all we can to bring some closure to Mr Roberts' family and friends.
