Winston Peters and his colleague Shane Jones have had their dinner with Gun City owner David Tipple

Tipple spent almost seven and a half thousand dollars to have dinner with the Ministers - which was meant to be for just two people.

Instead, there were almost 30 family members at Tipple's Christchurch home last night.

Jacinda Ardern says she was relaxed about the dinner and says it doesn't mean they agree with Tipple's opposition to gun law reform.

The Prime Minister says on most occasions when she sits down to dinner with people some at the table will disagree with her.
