The Associate Transport Minister says the Government has nothing to hide, but she still won't release a letter she penned when it was crunch time for a decision on Let's Get Wellington Moving.
Under pressure in the House today Julie Anne Genter did however reveal some details of the nature of the letter.
She said she expressed her concerns about the lack of sequencing of projects in the $6.4b transport project, including a second Mt Victoria Tunnel.
The letter sent on March 26 of this year to Transport Minister Phil Twyford has stirred speculation over just how much political power the Greens exerted over the project behind the scenes.
The Government endorsed LGWM package has shoved a second Mt Victoria tunnel on the back burner. Meanwhile doubling The Terrace tunnel and trenching Karo Drive didn't make the cut at all.
