CCS Disability Action Access Aware co-ordinator Raewyn Hailes said the problem of people using mobility car parks was "huge".
"There is a massive lack of social conscience ... We have found that for permit holders, the impact of this is that if they can't find a space, it often means they go home without doing what they needed to do.
"We are using the app to gather data which will then help us lobby the Government for legislation changes."
Hailes said councils were able to police public mobility parks but the bigger issue was abuse of private mobility car parks in places like supermarkets and parking buildings.
"People will use these car parks thinking they'll only be a minute but any permit holder will tell you it's never just a minute."
The app can be downloaded by any road user and there are currently 8500 registered users.
Hailes said the app received a large number of reports daily.
Rotorua Lakes Council's manager, community and regulatory services, Kurt Williams, said the organisation was asked to come on board with the app to help police the use of mobility car parks.
"We are supportive of the initiative and have integrated the app into our parking monitoring system. Our parking wardens receive notifications via the app, alerting them to vehicles using mobility parks incorrectly.
"Discussions about incorporating the app into our monitoring system began in July this year. To date the app has minimal use locally. Usage may increase with greater awareness of the app."
