State Highway 11 (SH 11) is a 30 kilometre stretch of highway in the North Island of New Zealand. It links at Puketona and at Kawakawa. Its main destination is the Bay of Islands township of Paihia. Until 2004, it terminated at Tohitapu Road, in southern Paihia township.
First gazetted in 1997,[1] SH 11 begins at a junction with SH 1 in Kawakawa. It heads north along the coast, passing west of Opua before entering Paihia along Paihia Road, Seaview Road and Marsden Road. It then leaves Paihia to the west along Puketona Road and passes through Haruru, before terminating at Puketona Junction on SH 10, 10km (10miles) south of Kerikeri.
SH 11 provides access, via Paihia, to the Waitangi Treaty Grounds: the location where the Treaty of Waitangi was signed in 1840.
