SH10 Bulls Gorge passes through the Puketona Scenic Reserve, home to a tributary of the Waitangi River and significant regional flora and fauna.

NZTA and its partners Northern Civil and Transfield Services have worked closely with staff from the Department of Conservation on a management plan to monitor and protect local fish and kiwis living near the construction area.

Fish friendly measures:

  • The tributary will be realigned and banks replanted, away from the road and construction
  • Three native fish species – koura (freshwater crayfish), banded kokopu and long-finned eel will be carefully relocated downstream during construction
  • A new fish friendly culvert will be built to give juvenile fish safe passage upstream to spawn

Protecting our national icon:

  • Extensive monitoring by the project team found 10 North Island Brown Kiwis living in the Puketona Scenic Reserve
  • Small transmitters have been attached to their legs to check their location each morning
  • Any kiwis found near construction activity will be carefully moved or work reprogrammed for another area
  • Best practice around daily kiwi monitoring was established during logging in the Waitangi Forest
