I was down that way a month or so back got some good shots at Bay of Islands. Couldn't get any shots at 12 Apostles it's obviously a no-go between 9am-6pm due to 12 Apostles Helicopters operations, we couldn't get there early enough.
Would love to shoot it in afternoon golden hour after 6pm when it's lit from the front but there is a handful of days down there per year it's not blowing a gale in the afternoon.
There is a lot of great places down that way, it really is one of the worlds best ocean road drives.
I will post up some footage once I get a chance.
