The Prime Minister is clearly feeling under pressure from the debate on the taxation working group's report.

Jacinda Ardern spent a good part of her post Cabinet press conference on what's being said about the Government's intentions.

Ardern says some statements are simply inflammatory.

"The notion that it's an attack on the Kiwi way of life is a broad sweeping statement. I have heard many untrue statements that it's a double tax and a death tax."

The Prime Minister says only a small number of people would pay a capital gains tax - but she gave a strong hint farmers and small businesses may not be among them.

"Small business and farmers are crucial to our economy and the effects on them will be at the top of my mind when options are assessed."

She says she welcomes the debate, but urges people not to make things up.
