More MPs and longer parliamentary terms have been deemed key to modernising a decades old electoral system. 

Fresh New Zealand Initiative research found 30 years on from the introduction of MMP, our parliament is in the need of a four year term and 50 more members. 

That would take the Parliament to 170.

Report author and Senior Fellow Nick Clark says MMP has delivered fairer and more representative parliaments. 

But he says these changes would create better balance between members and the executive. 

Clark says right now there is a huge number of ministers compared to members, making it harder for MPs to hold those ministers to account.
