Owen McShane runs a website called “Straight Thinking” which originally launched in 1995 in a a magazine format. According to his bio on the site, McShane's background is in architecture and town planning.
He is the director of the Centre for Resource Management Studies in New Zealand. The objective of the Centre, according to their website, is “the promotion of a heightened awareness and understanding of, and knowledge about, the environment and environmental issues within the community in New Zealand.” 
While this is the stated objective of the center it appears that the main purpose is to criticize the New Zealand government's Resource Management Act, which was established to balance commercial development with environmental protection.
Stance on Climate Change
“It must be coming evident that the science connecting Greenhouse gases to damaging climate change grows more tenuous by the day and the costs of using these theories to justify central planning of everything are causing Governments everywhere – but especially in Europe – to suddenly loose interest. They have real problems to deal with – not mythical conceptions of disaster in a hundred years' time.” 
“We are about to incur a host of taxes, levies and incentives, all driven by T-shirt slogans, which are, in turn, driven by junk science and junk economics. Any technologies we develop will address the needs of only those markets suffering similar distortions. We are unlikely to develop anything of use to Europe's nuclear sector or their waste-to-energy plants. We have already rejected both responses to the [Kyoto] protocol.”
“The real costs of Kyoto will be our loss of freedoms as we travel down this second road to serfdom.” 
McShane was a speaker at the Heartland Institute's First International Conference on Climate Change (ICCC1) where he gave a speech titled “Climate Change: The Last Gasp of Smart Growth.”  Video can be viewed below.
The conference was titled “Global Warming: Truth or Swindle,” and described as a “gathering of skeptics.” Heartland contends that this group lacks a “platform from which they can be heard,” as “Their voices have been drowned out by publicity built upon the United Nations’ Intergovernmental Panel on Climate Change, an entity with an agenda to build support for the theory of man-made catastrophic global warming.”
McShane was part of a group referred to as “Team Bali,” made up of numerous climate change skeptics including Christopher Monckton who attended the U.N.'s 13th Annual Conference of the Parties (COP) in Bali.
Part of the groups purpose was to “present information to the international media critical of the current state of climate science,” which was accomplished through a press conference arranged by the Committee for a Constructive Tomorrow (CFACT).
CFACT reported that “Team members Owen McShane from New Zealand and Dave Evans from Australia, among others, began carrying copies of the Global Warming Swindle directly into the media center and handing them out to anyone with a press badge.” 
According to a search of Google Scholar, Owen McShane has not published any articles in peer-reviewed journals on the subject of climate change.
