Johann Berg Gudmundsson and Jozy Altidore scored two each for AZ, with the home side's reply coming from Erolind Derguti.
Feyenoord also beat amateur opposition with a 4-0 rout of Rotterdam rivals XerxesDZB.
The Eredivisie side had to wait an hour to take the lead through an Anthony Bentem own goal before strikes from Terence Kongolo, Ruud Vormer and Lex Immers (penalty) gave the scoreline a one-sided look.
Ramon Zomer scored the only goal as Heerenveen edged out third-tier Hollandia 1-0.
