Park in the Karekare Beach carpark on Karekare Rd. Take one of the tracks above the north end of the beach and from there down to the beach.
Do not attempt to ford Karekare Stream if it is in flood and swift flowing. Watch out for rogue waves sweeping up the beach especially at stormy times. Only swim in the waves if the surf patrol is on duty and only swim between the flags. Do not attempt to climb the cliffs nor linger too long at their base. Beware of large waves surging up the rocks if you clamber around the rocks at the north end.
Access to the beach may involve fording Karekare Stream which may be 20-30 cm deep. Best to visit at mid tide or lower but still plenty to see at high tide. Walk to the rock cliff at the north end of the beach and also to the rocky point opposite the islet at the south end (or beyond if you are energetic).
