''Tui'' then opened fire on the barges, sinking one with her 4-inch gun, and the remaining two escaped inshore in the darkness.


Submarine ''I-17''

On 19 August 1943, while escorting a convoy from Nouméa, ''Tui'' picked up a submarine contact. She made an initial run over it without using depth charges, a second run dropping two depth charges, and a third run throwing another two depth charges. Contact was lost and ''Tui'' signalled some US

One of these indicated that ''Tui'' should investigate smoke on the horizon, where a submarine was sighted on the surface and ''Tui'' opened fire at maximum range, scoring one, possibly two hits. The aircraft then dropped depth charges and the submarine sank at . The submarine was the , 2,190 tons, long, built in 1939. Ninety-one crewmen were lost and ''Tui'' picked up six survivors who said that ''Tui''s depth charge attacks had damaged the submarine and forced it to the surface. The commanding officer and anti-submarine control officer on ''Tui'' had doubted whether the contact was really a submarine, so the depth-charge attacks were not properly carried out. A later Naval Board report concluded that "had the proper procedure been followed and a full depth-charge pattern fired in the original attack, there is little doubt but that the submarine would have been destroyed." ''I-17'' was the first Axis ship to shell the United States mainland when she shelled an oil refinery near Santa Barbara on 23 February 1942.


Other service

COMSOPAC released the New Zealand ships in June 1945, and ''Tui'' departed the Solomons escorting a group of six RNZN Fairmiles. On her return to Auckland, ''Tui'' worked with ''Kiwi'' and the 7th Trawler Group on the final clearing of the German minefield in the outer

Fate

''Tui'' was decommissioned for the last time on 22 December 1967. She was stripped of her equipment and sold in December 1969 to Pacific Scrap Ltd who demolished her. She was replaced in 1970 by a purpose-built oceanographic ship with the same name.
