Teina Pora's lawyers will this morning begin their fight to have his compensation payout adjusted for inflation - worth around half a million dollars.

He was paid out more than $2.5 million And given a government apology for being wrongfully convicted of the rape and murder of Susan Burdett.

Mr Pora spent 21 years in prison.

Law professor at Otago University Andrew Geddis told Mike Hosking these wrongful conviction payments are political decisions.

"We do it out of the goodness of our heart, not because we are legally bound to, and that's probably the main problem they're going to face when convincing the court to interfere here."

We hadn't thought it through, says the Greens. 

They are saying sorry for how their immigration policy was announced last year. 

The party wanted to cap migration at 1 percent of population growth but there were complaints the Greens were pandering to anti-immigration rhetoric.

Co-leader James Shaw said the policy was put together quickly and not thought through.

So he wanted to apologise to where it mattered most.

"We had the opportunity to speak at the Federation of Multi-Cultural Council and we thought, well these are the communities that we most want to communicate with. We took that opportunity to do it then."

Shaw said the party's immigration policy is now under review. "I think when we went out with that we hadn't really thought through all the implications of it, so it was hastily put together," he said.

Mr Shaw said a new policy should be out within weeks.

There's a minimal chance Kiwisaver will be made compulsory.

The man who created the savings scheme, Sir Michael Cullen said those who aren't enrolled probably need it the most, so the Government should consider making it mandatory.

But Prime Minister Bill English told Mike Hosking the argument against compulsion outweighs the other side.

"If people aren't saving, for a lot of them it's because they can't. Under pressure in their budget and if you make it compulsory you then need a whole complicated set of arrangements to deal with the people who just can't afford to save."

If Teina Pora wins in court the Government will pay up, says Mr English. 

Wrongly-convicted Mr Pora heads to court today to argue his compensation for spending 21 years in jail for a crime he didn't commit, wasn't inflation adjusted, so he should be paid around half a million dollars more.

"Well the court will effectively, as I understand it, decide whether there's a change in the payment or not", Mr English said. "I don't know if we'd have much choice about doing anything different in the court setting."WATCH THE FULL INTERVIEW BELOW

Shock in Italy as one of the Catholic Church's top officials faces sexual abuse allegations.

The third highest ranking Vatican official Cardinal George Pell has stood aside and will be heading back to Melbourne to face the charges.

Italy correspondent Jo McKenna said the charges were expected but it was still quite a shock for people in the Catholic Church.
