Why Join Us?

In a word: influence. The NIA exists to represent your interests; to make sure that your opinions are heard on vital issues. When government or other agencies propose new regulations, standards, or funding mechanisms, we’re there to ensure that policymakers understand and respect the views of industry professionals: the firms that deliver and are making a difference on the ground.

Feedback from individual businesses can easily be dismissed by the bodies that set the rules. But, as an association that represents all aspects of the industry, the NIA commands attention from decision-makers at the very highest level. We routinely engage with government, accreditation bodies and other agencies, and our input encourages them to develop policies that are practical, realistic and focused on delivering better outcomes for all. We have also developed unique agreements and relationships for our members with key service providers. This includes associate members/partnering agreements, such as specialist software, H&S / legal advice, etc.

You can also use the NIA to develop new knowledge and a better understanding of emerging opportunities and funding mechanisms. This can all help to inform and improve your business development strategies.

We exist only to serve the best interests of our members. The larger that membership becomes, the more impact we can deliver.

The NIA membership represents professionalism and the best practice in industry, recognised by clients and stakeholders.
