"The council wants to strengthen participation by seniors in council decision-making on behalf of the community," said Mrs Raukawa-Tait.
"An ageing population means council will need support, advice and advocacy by and for the district's older population.
"As we know, the number of older people is growing so it's very important to us that they have a voice and are able to have and encourage effective input into decision-making that affects their age-group now and in the future.
"Of course this is not the only way council will engage with this portion of our population but this is one, proactive way we can ensure we hear from those aged 50 and over."
Expressions of interest close at 10am on 10 July 2015. A maximum of 12 people will be selected for the Positive Ageing Rotorua group and shortlisted candidates will be interviewed.
