Manukau City and Lower Hutt's Stop Out have made the most of kinder draws to win through to the last 16 in the Chatham Cup, while Papatoetoe joined them after upsetting Onehunga Sports away from home.
Stop Out, whose run through to this weekend's third round included two upsets over Central League opposition, faced fellow Capital League side Upper Hutt and claimed an enthralling 4-2 derby win largely thanks to a first-half goal rush.
A frantic opening five minutes saw Upper Hutt's Javier Montalba and Stop Out's Fisum Aden trade goals before Stop Out took the lead through 14-year-old Cherbel Kouchaba midway through the half.
An Alistair Yates brace in the last five minutes of the first spell had the 1956 Chatham Cup winners 4-1 up at the break but Luke Grindlay struck nine minutes before fulltime as the home side threatened to claw their way back into the tie.
Meanwhile, Manukau City are a far as they been in the Chatham Cup since a semifinal loss in 1987 thanks to Rhys Ruka's 82nd minute winner against fellow Northern League second division club Mangere United in a tense battle in south Auckland.
