New Zealand has declined an invitation by Canada to join the Defence, Security and Resilience Bank, a multilateral institution currently under development that finances the defence industries of its member states, which contribute capital to be reinvested.
Committed countries include Ukraine and Turkey, alongside several European neighbours, with Canada leading the initiative.
According to Ministry of Foreign Affairs and Trade (MFAT) advice released under the Official Information Act, Canadian Prime Minister Mark Carney invited his New Zealand counterpart Christopher Luxon to take part in negotiations over the bank's charter in late April, and eventually to buy in as a partner.
MFAT officials advised ministers against taking up the offer in late July, noting an initial contribution of NZ$100 million, with costs expected to rise from there, along with ongoing commitments.
Officials argue that New Zealand's defence capacity would be better served by improving market opportunities rather than joining the bank.
