Foreign Minister Gerry Brownlee says additional sanctions on North Korea mean less money the country will be able to put into its illegal nuclear and missile programmes.
The United Nations Security Council adopted its ninth resolution for additional sanctions on Tuesday morning, following the rogue nation's latest nuclear test on September 6.
"These new sanctions send a loud and clear message to North Korea that its behaviour will not be tolerated by the international community and will be met with significant consequences," he said.
"New Zealand, once again, joins the international community in calling on North Korea to abide by its international obligations and turn away from its current course."
The sanctions include reducing North Korea's oil imports, and banning the country from importing natural gas and exporting textiles.
The number of North Korean labourers who can work overseas would also be restricted, while states could inspect vessels suspected of carrying items prohibited by the sanctions.
