Auckland has a different system to the medallion system, but still has restrictions:

  * The driver needs to have an endorsement on their drivers' license allowing them to operate a small passenger service vehicle. To get this, they need to pass a 'fit and proper person test' (which disqualifies many people with past convictions) and have completed a course.
  * The driver needs to be employed by an approved passenger service. It currently costs NZ$449.80 to apply to start a new one - the laws about when the government must grant them are here, http://www.legislation.govt.nz/act/public/1998/0110/latest/DLM434609.html and there are no direct limitations on the number of taxis.
