Auckland Transport has begun an internal investigation into the way it handled a complaint made on the social network Twitter.
An Auckland woman says it contacted her employer after she posted a tweet complaining about an increase in on-street parking fees.
In an exchange on the Twitter site, an Auckland Transport representative wrote of being mortified at the suggestion the agency had contacted the woman's employer.
Its spokesperson, Sharon Hunter, cannot confirm whether the employer was actually contacted, saying an investigation may take several days.
Ms Hunter says Auckland Transport has a clear policy about online privacy, and it respects the right of individuals to provide comments and feedback.
