ASB Bank commissioned King to come to New Zealand and create a series of fast clips with the Sevens players in action to depict the speed of the game they love.
The first video shows Sevens player DJ Forbes scrolling through picks of sunglasses on a smartphone and then with a "magic trick" flicks them on to the face of teammate Sam Dickson.
The second video has NZ Women's Sevens player Huriana Manuel punching flat rugby balls which "magically" inflate.
In the third video, DJ Forbes throws a rugby ball into the air which turns into a watermelon. He passes it to Sam Dickson who then throws it for Liam Messam to kick.
The watermelon smashes and Sam Dickson catches a piece and eats it.
