Quad Biking in Ahipara. Luckily one of the people we know up in Kaitaia is good friends with the people who rent out the quad bikes in Ahipara. From here you can go riding up 90 Mile Beach and the sand dunes. As this was our first time on a quad bike (and it was way cool) we stuck to the shoreline heading south from Ahipara. All the way along the coast were private little bays and people fishing, amazing sights and beautiful weather, but I got a bit burnt and am now sporting a bright pink pair of “lobster legs”.
