Parliament's Commissioner for the Environment has ruled out being a cheerleader for the use of 1080 after MPs questioned if she could do more to promote its use.
Jan Wright's report on the poison in June this year concluded that it is the best tool to combat possums, rats and stoats and that more should be used.
Dr Wright appeared before Parliament's Local Government and Environment committee on Thursday afternoon to talk about her reports into 1080 and lignite.
Some MPs questioned whether she could play more of a role in the debate on 1080.
But Dr Wright says her independence from Government means she should stay clear of trying to engage the public on the issue.
