Families of the 29 Pike River mine victims say the public expression of sympathy from former mine boss Gordon Ward is "hollow".
Mr Ward has broken his silence on the fatal explosions in November 2010, after refusing to front up to a Royal Commission of Inquiry into what happened - but the families say they will not accept his "excuses".
An influential figure at the mine for 12 years, Mr Ward was chief executive up until six weeks before the first explosion. When tracked down on the Gold Coast by a television documentary crew, he told TVNZ's Sunday programme he had cooperated with authorities investigating if there was any criminal negligence, but refused to comment on the commission.
He added: "I think it is an awful tragedy, and no one has been unaffected by it who has been involved with the company. It has had a tremendous toll on everybody".
"Words can't express the deepest sympathies I have for the families."
