The Newbury Principles collectively refer to an urban planning guideline stating that decisions should be made based only on the planning considerations relevant to the current development, even if the consideration of ulterior purposes may lead to a greater public good.

The Newbury principles are applied in Australia, and have been cited by courts in New South Wales and Western Australia.[2] [3] The Newbury test also remains in general application in the courts of New Zealand.[4]

In all instances the assessment officers must have regard for the contents of the development application at hand and the requirements of the EP&A Act and the Regulations to ensure that the development will meet legislative requirements.
