Birkenhead United and Manukau City are the surprise inclusions in the quarter-finals of the 85th ASB Chatham Cup, while Dunedin's big two made the most of home advantage to take their place among the last eight.
Birkenhead, leaders of the Northern League's first division, swept aside Premier League visitors Hamilton Wanderers on Auckland's North Shore with a 4-1 win that booked their first ever appearance in the quarter-finals of the competition.
A Graham Kay goal put Wanderers into the lead within the opening two minutes but a mazy solo effort from James Lawson, which started within his own half, evened the ledger five minutes before halftime.
Birkenhead pulled away after the break with Keegan Linderboom, Bill Tuiloma, and Jack Hobson-McVeigh all netting.
Second division Manukau City pulled off the shock of the round, upsetting first division Papatoetoe in a dramatic 4-3 fourth round penalty shootout win on Saturday after scores were locked 1-1 after extra time.
