Investment management system

The investment management system means the processes, rules, capabilities, information and behaviours that work together to shape the way investments are managed throughout their life cycles.

Within the Treasury, our work in this area is led by the Investment Management and Asset Performance team. Working alongside other State sector agencies, our ambition is to get the government investment management system working well. We wish to effectively turn intent into outcomes.

The investment management system is complex, with interrelated cycles spanning months or years. The system has to effectively convert business unit, agency, sector and all-of-government needs into outcomes in a way that gets the best value for New Zealand (given financial and other constraints).

The investment life cycle is made up of four phases: think, plan, do and review. Together these create an ongoing dynamic as ideas are tested, refined and adopted or discarded within an agency and across government. Each phase has different implications for agencies and decision makers.

A process diagram illustrating the Think - Plan - Do - Review approach.


Think - investment possibilities: To anticipate as much as possible what will be required to transition to the outcome, and satisfy the intent while maintaining services.


Plan - investment choices: To analyse and decide which investments to undertake considering the optimal overall value from the limited resources, and the current risk appetite.


Do - investment development: To give chosen investments the greatest possibility of realising the benefits promised, while maintaining controls to avoid loss of value.


Review - investment performance: To review the performance of investments against expectations. To encourage promised benefits to be realised and assets to be operated near optimal levels of performance. To use any lessons learned from the performance of investments to inform and improve the development of future investment activity.
