The terms of reference for the award is the winning coach of the New Zealand conference, but the danger of pinning the award to the outcome of one match was proven this year, with Fitzgerald having a negative win-loss record this season.
Also going back-to-back this year was Kayla Cullen, who took out the people's choice award in a count that came right down to the wire with less than 50 votes separating the top three.
After featuring strongly in her team's unbeaten run to the finals, Southern Steel midcourter Gina Crampton was named the NZ ANZ Championship Player of the Year.
Crampton, who made her international debut in last month's Constellation Cup series, collected the aspiring Silver Ferns award in 2015. This year the prize went to impressive youngster Holly Fowler, who will next season link up with new Auckland franchise the Northern Stars.
Presented for the first time in 2016, Netball Central's Karin Burger was named Beko Netball League Player of the Year.
Netball fans also voted for Netball South's victory in the inaugural Beko Netball League as their moment of the year. It was a double win for Netball South, with their coach Lauren Piebenga named national league coach of the year.
