Our partner organisations

IIA NZ collaborates with Information Systems Audit and Control Association (ISACA), RiskNZ and the Institute of Directors (IoD) to share information on best practice and run some of our events.

We are grateful for the support given to the Institute by those organisations that very generously allow us to use their venues for our events.

Our regions

We encourage everyone in the internal audit and risk management professions – members and non-members – to attend events run by IIA NZ regions.

Each region develops education and networking event programmes to meet ongoing professional development requirements, and provide members with the opportunity to network with a wider group of people.

Some networking events are free while others,particularly lunchtime meetings, may have a small charge to cover catering.

Education Days are held in Auckland, Wellington and Christchurch each year. Registration for these professional development days is moderately priced.

You can find more information about specific events on our Events calendar.
