The Police National Dive Squad is on its way to Lake Rotoiti to help look for a person who was seen to "go under" on Lake Rotoiti yesterday.
Police confirmed this morning they were still undertaking a search and rescue rather than a recovery operation but said they were unable to release specifics to the media.
Squad second in charge, Constable John Fredericksen, told the Rotorua Daily Post he was planning to speak to the family this morning to "ascertain whether they've advised all the people they need to".
He said police were still unable to release if the person was a man, woman or child or if the person was swimming, fishing or on a boat.
He said he hoped to release more details later today.
