A New Zealand man has gone missing in unusual circumstance in Australia.
Michael Junior Huria, who also goes by the surname Sullivan, hasn't been seen since leaving his home in Ellenbrook, Western Australia at about 4.15am last Monday.
Two days later his vehicle was located but there has been no sign of the Mr Huria, 23, who is believed to have links to Wellington and Hawke's Bay.
His disappearance is out of character, police say, and could possibly be linked to a car accident the day he went missing.
"As part of our investigation we are reviewing a report we received on Monday night regarding an incident in which a woman believes her car may have struck a pedestrian near the corner of Great Northern Highway and Apple Street, Upper Swan," Western Australia police said in a statement.
"The driver was not 100 percent sure, but believed her car and the pedestrian made contact."
Upper Swan is about seven kilometres from Ellenbrook, in Perth's outer north-eastern suburbs.
The search for Mr Huria has escalated since his disappearance was reported, and now includes police horses, a helicopter and state emergency service volunteers.
Mr Huria was wearing a white shirt and blue, possibly denim, shorts.
He was not wearing shoes and may have mud on him.
Family and friends on Facebook have appealed for anyone who has seen him to contact police.
"Darlings this is a difficult time for all of you stay strong united and trust the Lord is caring for Michael in his hour of need karaka is important and wrap yourself in love and never give up," his grandmother Margaret Sullivan wrote on Facebook.
