"Other notable people buried in the cemetery at Mangungu Mission include James Reddy Clendon - the man who supported the British Resident, James Busby, in his efforts to unite the northern tribes to prevent the Frenchman Baron Charles de Thierry from establishing himself as a 'Sovereign Chief' based in the Hokianga," he said.
"Clendon was also a principal witness to the signing of the Declaration of Independence in 1835 and the Treaty of Waitangi in 1840. He was also our first US Consul in New Zealand."
Another person with links to early New Zealand - and who is buried at the Mangungu cemetery - is Samuel Butler. The son of Rev John Butler, who oversaw the building of the Kerikeri Mission Station, Samuel Butler, had come to the Hokianga in 1827 where he tried to make a living as a shipping agent and interpreter arranging cargoes for visiting ships.
Life was hard, as Samuel recorded: "Times will not permit bread every day and drinkables are quite out of the question."
He must have found some drinkables however, as in 1836 he drowned after falling overboard while drunk, leaving his wife Ann to raise their five children.
Besides famous people in history, the cemetery is also the final resting place for many of the district's earliest settler families.
"The cemetery at Mangungu is an important archaeological site in its own right, and is well worth exploring," Mr Edwards said.
