National list MP Aaron Gilmore says the Parliamentary Service is responsible for an error that credited him with a high-level finance-sector qualification he does not have in a CV posted on his Parliament web page.
Until yesterday, Mr Gilmore was listed as a member of Chartered Financial Analyst (CFA) Institute.
Last week, however, the institute told the Herald that was incorrect.
Mr Gilmore said the error was introduced when someone at the Parliamentary Service wrote the biographical material for the page.
"I've never been a member of the CFA institute. I've been studying towards membership and that's what I've always said and that's what my CV says."
He described the error, which he had corrected yesterday, as "a cock-up by somebody else".
A spokesman said the Parliamentary Service did not discuss matters affecting individual MPs but biographical information about MPs published on its website was supplied by them and approved by them as correct.
The error was discovered by the Herald after Christchurch East MP Lianne Dalziel alleged there were "anomalies" in Mr Gilmore's online CV.
