Similarly, the Authority must be fully aware of all rights and obligations in relation to programmed maintenance and lifecycle replacement and should allocate resource with a technical background to ensure that proposals are fully and appropriately assessed. Any NZ ambitions should be aligned with existing commitments under the existing contractual arrangements i.e. the Project Agreement as far as possible. For example, the need to reduce emissions, and that wherever possible, maintenance or the replacement of equipment is done in a way that improves energy efficiency and reduces emissions. Authorities should work to ensure that these factors are considered in any investment decisions.
