The New Zealand Department of Internal Affairs has lodged a High Court case against Perth businessman Wayne Mansfield over an alleged email spam operation.
The department accuses Mansfield of using a number of email address lists to promote business and marketing seminars in New Zealand.
It alleges the unsolicited emails were sent to NZ addresses from a .co.nz domain registered to Mansfield or his agents, and that the servers and computers used to access the messages were located in New Zealand.
Mansfield faces a maximum fine of $NZ200,000 ($A153,813) under the Unsolicited Electronic Messages Act 2007 if found guilty, the department said.
He has 25 working days to respond to the statement of claim. No date for a hearing has been set.
Mansfield did not respond to request for comment.
Details of the statement of claim were also being sought at the time of publication.
