Civic society voluntary associations promote healthy ageing by increasing older adults’ social and physical activity levels and through the co-production of services aimed at other senior citizens. Local governments are increasingly interested in collaborating with such associations as a policy response to an expanding ageing population. Co-production requires a flexible, network-based governance approach, which has not been examined from the voluntary associations’ point of view. This study explores how voluntary associations perceive the relevance and usefulness of public policies aimed at promoting co-production of services for ageing citizens. The study is based on quantitative data collected through a survey sent to 1,060 voluntary associations (N = 571) in three Danish municipalities. We also studied municipalities’ policies relevant to co-production of services aimed at senior citizens. We found that all of these policies included the explicit ambition of network governance of co-production of services targeted to address healthy ageing issues. However, our study indicates that the voluntary associations perceive the actual network governance to be somewhat fragmented and the corresponding scope of co-production was limited, which indicates the failure of municipalities to implement policy goals. Accordingly, municipal co-production in this area could probably benefit from the use of relevant key performance indicators that can enable political-administrative monitoring in order to secure deeper implementation and political accountability that promotes healthy ageing at the local level.
