The 2012 Fast5 Netball World Series was the fourth staging of the annual World Netball Series, and the first to be played under the new Fast5 rules, which replaced the older fastnet rules introduced in 2009. The tournament was held at Vector Arena in Auckland, the first time it had moved from its previous host nation England.
The 2012 tournament was contested by the six top national netball teams in 2012. New Zealand won the final against England, to record their third World Netball Fast5 series title.
20 matches were played over three days, under new Fast5 rules. Each team played each other once during the first two days in a round-robin format. The four highest-scoring teams from this stage progressed to the finals, played on the final day of competition, in which the 1st-ranked team played the 4th-ranked team, while 2nd played 3rd. The winners of these two matches contested the Grand Final; the remaining teams contested the third- and fifth-place playoffs.
