In total there are 63 maps. The footer for each map describes the status as Operative 2013. The Hauraki Gulf Islands Section was made fully operative as of 22 March 2018.
Each map is further divided into map 1 and map 2:
- Map 1 identifies the location of land units, settlement areas (Great Barrier only) and significant ridgeline areas.
- Map 2 contains information about designated land, scheduled heritage items, natural hazard areas, other additional limitations and roading classifications.
It is important to look at both map 1 and 2 for any site.
