Earlier today, Sergeant Vince Ranger, of Waikato Police, urged people in the Hillcrest area and suburbs to check their backyards, sheds and other outbuildings in case Thatcher had taken shelter there.
"Thatcher is quite mobile, so he may have travelled quite a distance. Public in the Hillcrest area will possibly see police and SAR in their area today and they may be looking to search properties," he said.
"We are working hard to locate Thatcher and even the smallest piece of information could help, so please don't hesitate to contact us. If you see him, or have seen him, please contact police immediately."
