Those fears were heightened by some of New Zealand's major trading partners - such as the United States - refusing to sign the agreement.
Helen Clark said the policy package to be released at midday would be pragmatic. "I think it would be a most unreasonable person who said that all due care had not been taken."
Though the policy package could not be considered as being watered down, "the Government always had in mind a preferred policy position which was consistent with economic growth and development and meeting Kyoto commitment. We don't see the two in contradiction".
Energy Minister Pete Hodgson, who is in charge of the climate change project, will front the release.
In February Mr Hodgson released a national interest assessment of the Kyoto protocols.
The assessment was that as a climate-dependent, primary-producing country with significant populations in coastal areas, climate change presented a significant risk.
Disadvantages could include slower economic growth.
Under the protocol, New Zealand would have to reduce emissions to 1990 levels over five years from 2008 to 2012. At present, emissions are about 10 per cent above 1990 levels.
