WELLINGTON, New Zealand — The government of Australia’s most populous state ordered all public employees to work from their offices by default beginning Tuesday and urged stricter limits on remote work, after news outlets provoked a fraught debate about work-from-home habits established during the pandemic.

Chris Minns, the New South Wales premier, said in a notice to agencies Monday that jobs could be made flexible by means other than remote working, such as part-time positions and role sharing, and that “building and replenishing public institutions” required “being physically present.” His remarks were welcomed by business and real estate groups in the state’s largest city, Sydney, who have decried falling office occupancy rates since 2020, but denounced by unions, who pledged to challenge the initiative if it was invoked unnecessarily.
