The public have three days to tell the Chief Ombudsmen about their experiences making information requests to government agencies.
Dame Beveley Wakem's review of Official Information Act practices include 30-minute, confidential online surveys to gather feedback from requesters.
She said he OIA was a "crucial part of New Zealand's democracy".
"It is very important that OIA requesters - individual members of the public, civil society organisations, journalists, academics and businesses don't miss out on the opportunity to tell me about their experiences with seeking information from government agencies."
The surveys ask questions people may not have considered, such as their perceptions of agencies' attitudes to openness and whether they have ever been inhibited from making an OIA request, she said.
Survey forms are available on the Office of the Ombudsmen website.
