Kiaora bro,
It's a great video, the Naki has so many locations but only a few sandy beaches. Most spots have large course black granules (rocks).
I couldn't use booties just not the surf feel and you will eventually get tougher skin, some would sail out with booties but take them off out the back.
Most spots are right foot forward waveriding and there is a bit of local knowledge and a bit of driving will get you plenty on water time especially if you surf.
