The land where Phillips lived in hiding for nearly four years is private property, and investigators say people entering the area without permission will be trespassing.
Although cordons on Te Anga Road have been lifted authorities have urged the media and the public to stay away, and said the sites remain active crime scenes as officers gather evidence.
Phillips died on Monday after shooting and critically injuring a police officer during a confrontation following a burglary in Piopio.
Police said he opened fire after his quad bike was spiked, striking the officer in the head and shoulder before being fatally shot by officers. The injured constable remains in Waikato Hospital.
One of Phillips' children was detained at the scene of the shooting, and two others were located unharmed later that day in dense bush nearby.
The children are now in the care of Oranga Tamariki.
Since the incident, police have uncovered multiple makeshift camps where the family had been living. Items recovered include quad and trail bikes, tarpaulins, oil containers, tools, and even a toilet bowl.
Photos show tents camouflaged with netting and vegetation.
Detective Senior Sergeant Andrew Saunders said the evidence indicated Phillips had help from others.
