Prime Minister John Key is likely to set out tomorrow or Wednesday details of an inquiry to be held into his former minister Judith Collins.
Opposition parties are calling for a wide ranging Royal Commission into links between its ministers and the right-wing blogger Cameron Slater but Mr Key said it was his guess the inquiry would look only into the Judith Collins matter.
“New Zealanders need to know the Security Intelligence Service is being run properly, they need to know the ACC's been run properly.”
On Saturday, Ms Collins resigned after an email surfaced suggesting she had been involved in efforts to undermine the then Director of the Serious Fraud Office, Adam Feeley, in 2011. Ms Collins strongly denied her involvement and said she would fight to clear her name.
At the time, the office was looking into the actions of the failed company Hanover Finance.
Public law specialist Mai Chen said finalising an inquiry's terms of reference so quickly was unheard of.
