Early Ralston's career began with a cadet job for
South Pacific Television in 1979. In 1980, he worked as a general news reporter for
Television New Zealand (TVNZ) in
Wellington and
Christchurch. TVNZ seconded him to the
BBC for six months in 1981, where he worked as a reporter for
Wales Today in
Cardiff. Returning in 1982, he went to the New Zealand Parliament Press Gallery as a political correspondent for
TV ONE, where he covered the fall of the
Muldoon government. In 1999, an official from the
Ministry of Health visited Ralston and threatened to prosecute the magazine under the
Smoke-free Environments Act 1990, over a cigar review column. Ralston complained, saying the magazine derived no income from the column. While editor, several top Auckland restaurants banned him due to reviews in the magazine.
2000s In July 2000, police were called to a
Saatchi & Saatchi fundraising event, where it was alleged Ralston had punched guests. Ralston had a goal of reducing the $46 million TVNZ news budget by $4.5 million, He drew criticism in March 2005 for verbally attacking
Prime Television CEO Chris Taylor, saying, "I'd be shooting myself. I'd be pouring petrol over myself and throwing myself off Auckland's tallest building". He faced disciplinary action also in 2006 over an expletive-laden call to a
Herald on Sunday journalist, who was making enquires about a homeless cousin. Since TVNZ he has written columns for
The New Zealand Herald,
Herald on Sunday,
The Listener, the
Media Scrum blog for
Fairfax Media, and in 2009 was an afternoon host for
Radio Live. Former foreign minister
Winston Peters refused to appear on the
Sky News New Zealand show covering the
2008 general election, because he objected to Ralston, the host.
2010s At the
2016 Auckland local elections, Ralston contested the
Waitematā and Gulf ward of the
Auckland Council. He came second in the contest to incumbent councillor
Mike Lee and was not elected.
2020s As a former editor employed by the
Bauer Media Group, he commented on the company's decision to wind down its New Zealand business in response to the government banning magazines as part of the
coronavirus lockdown as follows: "Eighty years of the
Listener gone because some clod in Government decided to ban the publication." ==Recognition==
