Did Metgasco CEO write to then NSW Resources and Energy Minister Chris Hartcher and what did he say?

The Northern Star 10 February 2014:

LETTERS from Metgasco CEO Peter Henderson to various NSW ministers have gone missing, and Greens MLC David Shoebridge wants to know why.

Comments by Magistrate David Heilpern that the case against several anti-CSG protestors were vexatious and possibly politically motivated prompted Mr Shoebridge to lodge a GIPA (Government Information Public Access) request for correspondence from several ministers to see if he could find any evidence of political interference.

His request yielded a letter from Parliamentary Secretary for Police and Emergency Services, Geoff Provest, where he thanks Metgasco for their letters.

Mr Henderson told The Northern Star on December 9 last year that he had written to four government ministers in relation to the protests.

He denied there was anything improper in this and that he was requesting the "government's support through the enforcement of existing laws so that our approved operations could proceed safely."

But subsequent requests from Mr Shoebridge have turned up blank, with the departments saying they cannot find any letters.

Mr Shoebridge said that has increased his suspicion that key documents are being hidden.

"Metgasco have admitted to sending letters to four ministers, yet the Government has bizarrely denied having any record of this, despite the government's own correspondence with Metgasco referencing the company's letters," he said....

Liberal MP Chris Hartcher was the NSW Minister for Resources and Energy from 2 April 2011 to 9 December 2013. He is currently being examined as part of a NSW Independent Commission Against Corruption inquiry in relation to allegations that he and others corruptly solicited, received, and concealed payments from various sources in return for certain members of parliament favouring the interests of those responsible for the payments.

UPDATE

Hartcher has been suspended from the Liberal Party of Australia after being named in two major corruption inquiries.
