Here's a helpful video on the new hockey rules and the new rules are also set out below.
Good luck!
Procedures for taking a free hit, centre pass and putting the ball back into play after it has been outside the field:
a) the ball must be stationary
b) opponents must be at least 5 metres from the ball
If an opponent is within 5 metres of the ball, they must not interfere with the taking of the free hit or must not play or attempt to play the ball. If this player is not playing the ball, attempting to play the ball or influencing play, the free hit need not be delayed.
c) when a free hit is awarded to the attack within the 23 metres area, all players other than the player taking the free hit must be at least 5 metres from the bal
d) the ball is moved using a push or hit
e) the ball must not be raised intentionally directly from the free hit
f) if the player taking the free hit is the next player to play the ball, the actions of taking the free hit and of next playing the ball must be two separate actions
g) before another player of the team which took the free hit is allowed to play the ball, the ball must move at least 1 metre
The ball does not have to move 1 metre before the player taking the free hit may play the ball again.
h) from a free hit awarded to the attack within the 23 metres area, the ball must not be played into the circle until it has travelled at least 5 metres or has been touched by a player of either team other than the player taking the free hit
