New Zealand is a prominent player on the world stage. The women, having just missed a bronze medal at last year's Olympics, are ranked third, behind the Netherlands and Argentina; the men have just risen a spot to No5.
"New Zealand has a strong history of hosting some of the world's best sports events," outgoing Hockey New Zealand chief executive Hilary Poole said. "Attracting an event of this scale to Auckland would be incredible for the profile, development and growth of the sport in both New Zealand and the wider Oceania region."
Pledged support has already come from local and central Government.
HNZ submitted the bids on August 31. This is the first time the FIH have run a bid allocation process for their major events.
The quadrennial World Cup is up with the Olympics at the pinnacle of the sport. The World League finals, used to find qualifiers for the World Cup, are split between Rosario for the women in December, and New Delhi for the men in January.
