Prototype Topo50 front cover.

The front covers of Topo50 maps include important features such as:

  • a new design to easily distinguish it from the previous NZMS260 series
  • adjacent sheet names on the reference panel
  • an awareness panel to indicate the maps are "Used by New Zealand Emergency Services"
  • use of different sheet numbering. For example, Christchurch area was "M35" and will now be "BX24".
