The Government says there won't be a decision on Ihumātao this week.

Last week, Simon Bridges claimed he had it on 'excellent authority' there'd be a deal struck soon.

He claimed it would be announced this week while both Prime Minister Jacinda Ardern and Deputy Prime Minister Winston Peters are out of the country.

Finance Minister Grant Robertson says Bridges is wrong.

"That's not a surprise that Simon Bridges was wrong, as he was in this case. We're making progress, but this is a complex situation and one where we've got to bare in mind the interests of Fletchers and the whenua groups, and we'll keep working on it."

When asked whether it'll take 'up to seven months' for a decision, like Fletchers suggested in their earnings statement last week,- Robertson says it's not "a realistic possibility".

"Everyone involved in this scenario is frustrated by the time it's taking. That's because it's complex. We put ourselves forward to broker a deal, and we're coming to do that work."

Asked about the news that Radio Sport has given up the rights to air commentary for New Zealand Cricket, Robertson says that he hopes that it will be picked up by another service.

He understands there are a number of interested parties, so he does not think that it would reach a point where Government funding would be needed to keep it free to air.
