Mr Kumar questioned the previous owner about the safe but they also knew nothing about it.
He had discovered the body of the safe in a storage cupboard, under the stairs behind a wall.
"I Googled it and if it's original and not a replica, it is very unique."
Curiosity got the better of Mr Kumar and he called a locksmith to open it but they needed more tools to do the job. He has decided to open it later.
"If there is something in there that is good."
But now he was busy trying to authenticate the safe.
Landlord Coralie Rose, who has owned the building for more than two years, was excited to learn of the discovery when the Bay of Plenty Times contacted her.
"It's wonderful and I am very excited to know the history about it. It would be great if there was some gold in it but knowing jewellers it would probably be completely empty once they left."
Tauranga City information services librarian Debbie McCauley said in 1934 it appeared that the business was Clinkard & Co Seeds and Flowers.
It looked like Jack Fenn had his business, Fenn's Jewellers in the same building, where businesses had come and gone.
