Too many to list.
There would be upwards of 50 hockey stick suppliers around the world. Each has several lines (taken to mean between 5 and 10, depending on the size and focus of the company), and each line usually has between 5 and 10 sticks - some with many more. Besides this, there are extras like goalkeeping sticks, of which most companies make two or three (on average) and choices in stick such as length and weight, and for Ice Hockey the curve as well. Basically, you are looking at ten thousand sticks in total.
Some use one for their whole playing time; others can churn through two sticks a season. In total, an average player will have two or three sticks for the time they play.
Hockey New Zealand, the national body administering field hockey in the country, recorded 45,581 registered players in the 2011 winter season - from primary school players up to the Black Sticks national teams. This is a little over one percent of the New Zealand total population. 52.7 percent of hockey players in New Zealand are female.
