It was also the first time that Waitangi Day was formally celebrated on the site where the Treaty was signed.
Waitangi Museum curator Kate Martin said the 1934 gifting ceremony was a massive event for the Bay of Islands, with around 10,000 people turning up, including delegations from many iwi around the country.
"That's a huge number of people, especially when you consider that the roads in those days were not the best to travel on," she said. "That's also when Lord Bledisloe unveiled the foundation stone for the whare runanga."
One of the photos was of Te Arawa leader Mita Taupopoki. Another of the photographs showed Lord and Lady Bledisloe being led on to the treaty grounds.
Mr Gillespie said it was amazing so much information had been found so quickly and the people in the photographs identified.
"It was worthwhile bringing them in then. I didn't realise my parents went there that early."
