The Finance Minister says revelations she wanted to keep numbers attending this year's Budget lock-up more restricted than she suggested is a mountain out a of molehill.

After a wave of criticism directed at Treasury for restricting lock-up numbers - Nicola Willis said she stepped in to enable more people in.

An extra 30 people were added to the list.

But new OIA documents show it was actually Willis who pushed for tighter restrictions

She says she had initially opted to stick to the same approach for the Budget, as had been used for the half-yearly fiscal update.
