Three divers and two crew travelled from Wellington with their specialist equipment and conducted grid search dives at Bulmers and Arapuni landings, as well as shore search dives of both lakes.
Nothing was found.
Detective Senior Sergeant Ross Patterson of the Waikato West CIB met the Arohena community yesterday to update them of progress and answer questions.
He says locals want to help in any way they can to locate Richmond.
He says anyone who has any information should contact Detective Sergeant Paul Van Der Zee of the Te Awamutu CIB on 07 8720100 or anonymously contact Crimestoppers on 0800 555 111.
