Content management vendor Objective -- one of the state's approved suppliers -- has picked up the work in a contract awarded in June, a spokesperson for the vendor told ZDNet Australia via e-mail today.
DNR manages land and water resources in NSW with the aim of ensuring their long term sustainability.
In a statement to the Australian Stock Exchange (ASX), Objective said the rollout would also affect other stakeholders such as Catchment Management Authorities (CMAs) and the NSW Department of Planning.
This is due to the reliance by those bodies on services provided by DNR's Corporate Services division.
"Objective will capture and manage information and support business processes for DNR, 13 CMAs and the Department of Planning," the statement said. "The initial project will focus on deployment to the CMAs throughout NSW."
The Objective spokesperson declined to reveal the value of the deal.
