Decision Framework for Johnsonville Library, New Zealand

The problem

The Johnsonville public library, in a suburb of Wellington New Zealand, had become too small to meet the needs of the growing population. It needed to cater to the 10 000 more people who were expected to live in Johnsonville over the coming 20 years.

Autostop Group, a property developer, realized the Wellington City Council (WCC) needed a framework to systematically evaluate the four options they had to develop a larger library. The developer knew that the New Zealand public sector lacked experience in procuring public-private partnerships.

How we helped

Castalia provided a framework to systematically evaluate the costs and benefits of engaging a private service provider compared to owning, designing and building the facility. To help WCC assess both cost and service quality in the new library, Castalia identified five characteristics of value for money in provision of facilities.  We also illustrated the benefits of engaging private service providers by presenting three case studies and made suggestions to WCC for using the framework to select a procurement approach.


In 2015 the WCC decided against public-private partnership and elected to build a new NZ$22.5 million library as part of the Johnsonville Community Centre. Construction of the 1800Waitohi library began in January 2018, and it is expected to open to the public in December 2019. Castalia analysis indicated that a PPP would have resulted in the citizens enjoying a new library 6 to 7 years earlier.
