Former Prime Minister John Key says farmers will be eagerly awaiting the upcoming Tax Working Group report.

The group expects to hand its final report to the Government next week.

It will include a number of recommendations on how to make our tax system fairer.

Sir John Key told The Country's Jamie Mackay farmers might not be happy about some of the report's recommendations.

"Partly you've got concerns and questions being raised about what this tax review might do and what it might mean in terms of increased capital gains to farmers."
