The Prime Minster says he's proud of the India Free Trade Agreement and isn't phased by Labour's raised red flags

Opposition leader Chris Hipkins says they want the un-redacted advice about the deal and greater protection for migrant workers - to get Labour's support.

He also wants clarity about the clause requiring New Zealand business to invest 33-billion dollars into India.

Chris Luxon says the letter's just politicking and it's an awesome deal.

He says they'll work through their concerns - but it's frustrating when other parties don't get on board with growth.
