Hello everyone

Over the years, I have been uncovering the people buried at Camp Bay Quarantine Cemetery. I've listed my findings at Find a Grave. There remains one man who I have not been 100% sure about: Mr. Albert L. Butler. What I am seeking is your expert opinion and feedback...or any thoughts you may have regarding his death and burial.
Please let me provide you with the background:
Mr. Butler was a saloon/cabin passenger on the SS Lady Jocelyn. His death certificate says he died from consumption on November 11th 1872 - the same day the ship entered Lyttelton Harbour and came to anchor off of Ripapa Island at 4pm. Close to about an hour previous to that, the Lady Jocelyn had been inspected by the Emigration and Health Officer, who discovered that Mr. Butler had recently died (including the information of one other death earlier during the voyage).
What is uncertain was whether he died at sea or in harbour, and what happened to his body. Looking at passenger lists in the newspapers, Mr. Butler, it appears, had travelled alone. The ship's doctor, the surgeon superintendent, wrote his report November 11th and Mr. Butler is not mentioned - only the death of the other passenger.
The passengers were landed on the morning of November 12th.
Normally, cabin/saloon passengers are buried in a private or public cemetery - I researched (with help) and there is no record of Mr. Butler being buried at any of the local church cemeteries or public cemeteries around the Lyttelton area.
My own personal conclusion is he died and his death went unnoticed until the officers made their inspection and because he was on his own, his body buried at Camp Bay Quarantine Cemetery.
