Howieson was an unused substitute in their earlier games but came on as a substitute for West Brom's Chris Wood after 64 minutes of the 4-3 win against the Solomon Islands.
Wood had scored a first half hat trick to give New Zealand a 3-0 lead at the break but Cameron was introduced with the hosts having brought the score back to 3-2. They equalised on 88 minutes before Shane Smeltz scored a stoppage time winner for New Zealand.
The win takes them into the next phase with New Caledonia, Solomon Islands and Tahiti with the winners then facing a game against a team from North, Central America and the Caribbean for a place in the 2014 finals in Brazil.
Both Howieson and Edgar, as we reported yesterday, were winners over the weekend but there was no such luck for former Claret Leon Cort who won his fifth cap for Guayana. They were defeated 3-1 against Mexico in the Azteca in Mexico City.
The INTERNATIONALS feature has all been updated.
