"Significant time has been spent reviewing the original search, and although no issues were identified, police and LandSAR wish to search further areas of interest."
Wong Too said police were hopeful of finding evidence that Roberts had been in the area.
"We also wish to test and use new digital SARTrack technology that allows search management to better record and review how searchers search a particular area and debrief them more effectively so that we can identify items or areas of interest to the search."
He thanked the local community, including Uruti School and Uruti Community hall, which would host the crew of about 70 during the weekend.
He also thanked the search crews for giving up their personal time.
"LandSAR personnel give up significant personal and work time each year to train and deploy to assist the missing, the injured and the lost.
"Without the support of their families and employers we would not be able to respond in the timely and professional manner we do."
