Manawatu police searching for missing Pahiatua woman Elizabeth Udy are taking to the water using canoes and kayaks to find any trace of her.
Udy, also known as Lizzie, was reported missing on October 11.
Police believe she may have entered the Mangatainoka River by the Pahiatua Town Bridge.
Part of the search today, which has continued for more than a week, involves canoes and kayaks on the river.
"It is possible Lizzie may have entered the river on the boundaries of Pahiatua," police said in an earlier statement.
"Despite a week of land and water searches, police have been unable to locate any sign of Lizzie or information concerning Lizzie's current whereabouts.
