Bantamweight James McGivern, light-fly Stephen McKenna and light-welterweight Aidan Walsh brought Team NI their first ever boxing golds at the Commonwealth Youth Games in Samoa, while lightweight Tiernan Bradley and light-middleweight Brett McGinty both earned silver.
The success ensures that the team, coached by John Conlan and Damien Kennedy to 17 wins in 19 bouts, will finish the Games as the most successful boxing nation.
Yesterday's achievements were not just limited to the ring, with two other athletes contributing to what is now the country's best ever medal showing at the Games.
Larne's Conor Ferguson earned silver in the 200m backstroke to add to an earlier silver in the 50m backstroke and a bronze won in the 4x50m relay alongside James Brown, Emma Reid and Danielle Hill.
City of Lisburn Athletic Club member Ben Fisher was also among the medals after he took bronze in the 110m hurdles, matching his long jump achievement from Monday.
