Four Land Search and Rescue teams completed the search of the area but didn't find anything.
"These guys put some long hours in, because they really care about people," Fraser said.
The search sparked back into action at the weekend after reports someone fitting Peterson's description was seen in the area.
Fraser said since then, people of Rerewhakaaitu had driven the streets and left food outside their homes in case Peterson needed it.
Search and Rescue team leader Tony Middlemiss said people didn't realise the physical hours that got put into a search by the volunteers.
"These guys do not get the notoriety they deserve, they give so much of their own time, equipment and money."
He said Search and Rescue could never have too many volunteers.
"Any volunteer is welcome, you can lodge an inquiry on the website and if you're prepared to learn, then we will train you."
Matt Gare has been a Search and Rescue volunteer for the past two-and-a-half years.
"It's a way to give something back to the community," he said.
"It keeps me out of mischief."
He would estimate he has been involved with about 20 searches.
Yesterday was his fifth day involved in the ground search for Peterson and he had walked close to 17km.
He said he wanted to help get closure for the family.
"They need as many people as they can get on an operation like this.
"There's still morale among the teams and we are optimistic we will find him."
Gare said if Search and Rescue called and needed him to go out searching somewhere, he would go.
"It's always a blast, I enjoy the camaraderie of it."
