Port of Napier

Guardian helps safe navigation of vessels around the Pania reef at the entrance of New Zealand’s busy Napier Port.


  • With over 650 ships including 60 passenger ships docking every year, Napier Port is one of the busiest commercial ports in New Zealand.
  • Situated on the east coast of the country, there is a hazardous reef running northeast just a quarter nautical mile from the port entrance.
  • The formidable reef had five physical buoys to warn vessels but in bad weather and low visibility, remained a dangerous natural hazard.


  • Local authority Hawke’s Bay Regional Council employed Guardian from Vesper Marine to transmit virtual marks that ring fence the reef.
  • Ten virtual marks are used, including five marks that supplement the physical buoys.
  • By using the Guardian cloud solution, the virtual marks can be moved around easily by the Harbormaster from a remote computer to manage changing weather conditions.


  • In the three years since the solution went live, there have been no incidents around the reef.
  • Since the reef is clearly visible on ships’ onboard nav systems, the Guardian solution helps safe navigation in extreme weather and poor visibility.
