The search for a person seen struggling in Waikato River on Tuesday evening is now focused on the riverbanks around Waipa.
Police said they received a call from a member of the public who saw a person in trouble in the water near Victoria Bridge in Cambridge at around 8pm.
At this stage it is unconfirmed how the person came to be in the river.
A search was launched immediately and continued into the early morning.
A Search and Rescue team resumed the search on Wednesday and is carrying out a sweep of the river.
