A political analyst says Chris Hipkins is playing a dangerous game in choosing not to spread the load among his MPs.

Kiri Allan has resigned as Justice Minister after crashing a car on Sunday night - she's been charged with careless driving and refusing to accompany police.

Police Minister Ginny Andersen is taking over the Justice portfolio.

Political analyst Bryce Edwards told Kate Hawkesby it adds up to a lot of weight on her shoulders.

He says it goes to show Hipkins is making the same mistake as Jacinda Ardern, by loading up too few Ministers with too many heavy roles.
