Stuart Nash has been sacked from all of his ministerial portfolios, following further revelations of Cabinet rule breaches.
Nash emailed businesses associates in 2020 when the government was negotiating a commercial rent relief package.
He said he had lost an argument at the Cabinet table, and disclosed his colleagues' views.
Prime Minister Chris Hipkins says this breach carries more weight than the other rule violations that have recently surfaced.
Political editor Jane Patterson spoke to Corin Dann.
