The Greens have made it clear today they want to be part of the Labour-led Government - not just observers from the sidelines.

The co-leaders of the party have again today met with the Prime Minister and her senior team.

Marama Davidson believes they're almost there.

Davidson says they're making good progress and with all the to-ing and fro-ing over the past week it's now about narrowing things down and reaching the final point.

She thinks that'll be done by Friday.

Meanwhile, one of Auckland's biggest supermarkets has been slapped with a hefty fine for overcharging customers.

On six dates in June and October 2018 - mystery shoppers found Pak’nSave Mangere was charged more at the checkout than the promotional price advertised on the shelf.

Commerce Commission Chair Anna Rawlings says they found numerous discrepancies.

On four occasions, sliced salmon was displayed at $8.99 but charged at $10.79 -- and on two occasions, mushrooms were displayed at $4.99 but charged at $6.99.

The supermarket now has to pay almost $80,000.
