Labour's criticising the Prime Minister regarding his knowledge of legislation on bootcamps. 

The Government is crafting law to allow the use of force for restraining youth offenders at the military-style academies.

The Prime Minister has said he wasn't aware there were suggestions force could be used. 

Labour MP Willow-Jean Prime says that's not okay.

"It is deeply concerning that the Prime Minister is not across the details of one of the key National Party election policies, which is boot camps."
