Surf down here is great. The west coast is the best but places like Gisborne (east) are epic too.
Breaks like Raglan are famous and Piha is close to Auckland.
Orewa suits grandpa and grandma types just fine. That said a couple of kids drowned on an even "safer" beach a few years back when they got caught in a rip, panicked, ditched their boogie boards and tried to swim for it. Unfortunately a woman who tried to help died too, which goes to show that no beach is ever "safe".
If you ever did make it down here for a surfing holiday you'd go home a very happy surfer
