Walking Access Commission chief executive Mark Neeson says the system uses geographic information technology (GIS) to identify land that is open for recreational use.
He says high-quality, accurate information is brought together in one package, and will be of value to all New Zealanders.
Mr Neeson says it will also give landowners more accurate information on their own boundaries and on where people should, or shouldn't, be walking.
Over the next six months the Commission will look at making the information portable so it can be downloaded to a cell phone.
