Crown prosecutors claim an Auckland couple's murder in their Ellerslie home two years stemmed from road rage

Lok Fung Lorrence Li is accused of murdering North Shore orthopaedic nurse, Fuk-Fu Joseph Kwok - and his wife, Mei Han Chong.

The 27-year-old accused had a minor fender bender with Kwok that went before the Disputes Tribunal.

Kwok's personal details were released despite his request they weren't - and he and his wife were killed four days later.

Li is separately charged with conspiracy to murder his landlady.

Co-defendant Shu Man Poon this week gave a statement to police and will appear as a witness.
