Peter Wilson: Week in Politics -Treasury's grim forecast doesn't deter Willis

Treasury's latest forecast shows the extent of the economic challenges facing the government, but Nicola Willis isn't backing down on delivering tax cuts; Christopher Luxon goes to Sydney, vowing New Zealand will be a "bedrock partner" in regional security; and Parliament adjourns for the year after another burst of repealing zeal.

Finance Minister Nicola Willis is facing a difficult year balancing her tax cuts against deteriorating economic conditions, but there's no way she's going to back down.
