Editing Exit number (section)

===New Zealand===
New Zealand began introducing exit numbers in the Auckland region in 2005. It uses a distance-based numbering system. The distance to the exit is measured from the origin of the highway. That is:
* State Highway 1 (Northern and Southern Motorways) measured from the origin of SH1 at [[Cape Reinga]]
* State Highway 16 (Northwestern Motorway) measured from the origin at the Port
* State Highway 18 (Upper Harbour Motorway) measured from the origin at SH1
* State Highway 20 (Southwestern Motorway) measured from the origin at SH1

There is no exit zero. If there is an exit within 1.499&nbsp;km of the origin, Exit 1 is used. Exit 2 would be between 1.500 and 2.499&nbsp;km of the origin. Subsequent 'exit zones' are at 1&nbsp;km intervals. Letter suffixes are added at multi-exit interchanges, or where two or more exits exist within the same exit zone. For example, State Highway 1 (Southern Motorway) has an Exit 429A (Symonds St), Exit 429B (Wellesley St) and Exit 429C (Port). Instead of replacing existing ramp and link signs, the exit numbers were added as supplementary information. Thus drivers can navigate either by exit number or name. Exit numbers are only used for exits that may be used by all vehicle types. Bus- or emergency vehicle-only exits would not be numbered.

Exit numbers are not used outside the Auckland region.
