The New Zealand Government faces a high-stakes decision next year on whether to replace the Royal New Zealand Navy’s ageing Anzac-class frigates with the Japanese Mogami-class warship, a model recently chosen by Australia, according to Just Defence spokesperson Kevin Hackwell.
The Cost Realities of Modern Frigate Procurement
Frigates carry exceptionally high price tags for both purchase and ongoing maintenance. According to Hackwell, their primary operational function—defending United States aircraft carrier strike groups—requires high operational speeds alongside complex sensors, heavy weaponry, and advanced combat control systems that drive up expenses.
Did you know? The Japan Maritime Self-Defense Force operates the Mogami-class frigate, which was showcased during a port visit by the warship JS Kumano to Wellington in May 2025.
International Precedent and the Australian Connection
New Zealand’s potential acquisition follows a major procurement shift across the Tasman. Australia recently locked in an agreement to purchase the Mogami-class warship for its own naval fleet.
