Resources Minister Shane Jones said opposition to the fledgling industry was rooted in “shrill” environmental alarmism and “luxury beliefs” that ignored the need for economic growth.
New Zealand backed a ban on deep-sea mining under former progressive prime minister Jacinda Ardern in 2022, citing the risk of “irreversible” damage in poorly understood ecosystems.
However Jones, a senior minister in the governing centre-right coalition, said officials were rethinking that stance.
“We’re talking about this with our foreign affairs minister,” he told AFP in an interview.
“We can’t deny ourselves the option where critical minerals have an increasingly critical role to play.
“We can’t afford these luxury beliefs that have been imposed upon us.”
Companies stand to earn billions of dollars by scraping the ocean floor for polymetallic nodules that are loaded with manganese, cobalt, copper and nickel — metals used to build batteries for electric vehicles.
But the industry faces sharp criticism from scientists and environmental advocates, who fear new techniques could wreak havoc in poorly understood ecosystems.
“I personally think that seabed mining has become the last green trophy, so people are tossing around the most absurd, untested theories,” Jones said.
“And I’m not going to back down from these shrill voices.”
Jones was unruffled by suggestions a pro-mining stance could weaken support among New Zealand’s climate-threatened Pacific Island neighbours.
“I understand there’s a lot of theatre and posturing that happens when small island nations go to international fora,” he said.
“We’ve imposed upon ourselves an ideological corset, which we can no longer afford to wear.”
Deep-sea mining is one of the few issues on which Pacific Island nations are divided.
Nauru and Tonga are pushing for deep-sea mining in international waters, while Palau, Samoa and Fiji are staunchly opposed.
Canada-based The Metals Company has been working with the Nauru government in the hope of starting mining by 2026.
Harvard-educated Jones recently unveiled a pro-mining agenda differing wildly from the environmentally friendly policies of Ardern’s former government.
Under Jones, the isolated island nation will look to dig up everything from critical minerals to coal and iron-rich sands at the bottom of the sea.
New Zealand’s desire to scoop up this sand differs from deep-sea mining, which targets polymetallic lumps nestled in much deeper waters.
