Former Australian foreign minister and NSW premier Bob Carr intends to sue New Zealand Deputy Prime Minister Winston Peters for allegations made about Mr Carr's closeness to China, as a stoush over AUKUS turns feral.
The Labour opposition called on Prime Minister Chris Luxon to sack Mr Peters after the veteran called Mr Carr "nothing more than a Chinese puppet" and more on Radio NZ on Thursday morning.
New Zealand is mulling involvement in pillar two of the military tie-up, which will see AUKUS members - Australia, the UK and US - developing and sharing advanced warfaring technologies with other nations.
