Environmental management

Updated: 29 September 2010

Reflecting NZTA's desire to protect important sites the PA Site near the Karapiro Stream Gulley has been the subject of detailed investigation resulting in many interesting historic discoveries including evidence of fortifications.  As a result of the detailed study since 2007 there have been adjustments to the road alignment to protect the integrity of the fortified section of the historic site.

The NZ Transport Agency is committed to improving the contribution state highways make to the environment and social wellbeing of New Zealand by:

  • protecting and enhancing the environment
  • using and managing resources efficiently
  • considering environmental issues early
  • contributing to sustainable outcomes by working with others
  • continually improving environmental performance.

Noise control

Noise levels will comply with the latest standards.  Measures used will include:

  • Monitoring of noise during construction and advance notification of any unavoidably noisy construction activity.
  • Haul routes for moving materials will be away from main roads and sensitive residential areas wherever practicable.
  • Landscaped buffer zones and noise barriers to protect local residents, businesses and sensitive areas from road noise.

Visual impact, landscaping and environmental measures

Careful consideration will be given to native wildlife and habitats in order to minimise impact and disruption.

Landscaping and planting will be used to mitigate the visual impacts of the new road and create a pleasant environment for both road users and others.

Culverts will be used and plans developed to manage natural water flows and drainage.

Significant sites – Cultural, historic and environmental

To protect this history the following measures will be used:

  • protocols and agreements with local Iwi
  • engagement of cultural heritage monitors
  • liaison with local historical groups
  • on site archaeological controls to ensure that approved processes are followed.
