Police searching for a woman missing since her vehicle crashed into the Waikato River have asked landowners bordering the river to look out for suspicious objects in the water.
Sergeant Craig Singer, officer in charge of the Hamilton Missing Persons Unit, said police had already searched by boat for 40-year-old Eunki Kim, whose car crashed off a bridge two weeks ago.
``As water levels fluctuate with the heavy rains over recent days, we're asking landowners to keep an eye out for objects of concern and if they notice anything to contact police,'' Mr Singer said.
Police also want to speak with one of the original witnesses to the crash who left the scene before officers could interview him on June 6.
Mr Singer said the witness was a man believed to be in his 40s who was driving a silver or white Mazda 323.
