It's emerged the Prime Minister's Office approached Parliamentary Services more than once regarding the Henry Inquiry into the leak of the Kitteridge report.
Labour and the Greens are alleging Mr Key acted unconstitutionally and placed undue pressure on Parliamentary Services, and that led to Fairfax reporter Andrea Vance's movement and phone log records being accessed.
Yesterday the Prime Minister revealed his chief of staff did email Parliamentary Services but he maintains it was to do with obligations regarding ministers.
Now cabinet minister Steven Joyce has confirmed another email was sent in late May.
"The second one is a very, very short email which simply says 'Thanks for that', or something along those lines, and is not in relation to Ms Vance."
Meanwhile, double standards are being alleged as the political bunfight over the Henry Inquiry's actions continue
The opposition's been attacking the Government alleging the Prime Minister's chief of staff's pressure was what resulted in a journalist Andrea Vance's phone and movement records being obtained.
But Cabinet Minister Steven Joyce says they're being contradictory given just a short time ago they were baying for emails between MP Peter Dunne and Ms Vance to be released.
"And now suddenly they're holier than thou about the privacy of that information, you can't have it both ways Mr Robertson."
