"Ed was a highly valued colleague who made a significant contribution to a wide range of environmental issues both in his time at the Ministry for the Environment and over the last two years in the office of the PCE," he said. "The entire team is shaken by his untimely death."
His death has been referred to the coroner.
Police said the body was located at 10am on Tuesday with assistance from a drone.
Eighteen Land Search and Rescue (SAR) staff were deployed in the field, as well as six more in communications and oversight functions.
Surf Life Saving provided an IRB and four people, while the rescue helicopter was also involved, along with a three-person drone crew from Fire and Emergency New Zealand and 10 police SAR staff.
High river levels and bad weather conditions on Monday evening meant the search in the Ruahine Forest Park had to be delayed until Tuesday morning.
The search resumed at 6am, near the bottom of Gold Creek Ridge Track in Ruahine Forest Park, where it and the Sparrowhawk Track meet the Makaroro River.
