In 1898, aged 66 years of age, the electoral roll for Greytown show William as a baker.
Somewhere between then and 1900 he retired, and was classified as a “settler”.
From 1902 to 1904 he identified as a “mining expert”. Consulting mineral maps of New Zealand, it is doubtful any deposits of significance were or are found in this area.

WJR writes: I then went to the Mahaiopura diggings and since then have had varied experiences, spending a great deal of time prospecting for minerals in the Tararuas. I do not think that there is any gold there worth working for, but I do think the prospects for coal are good, and possibly tin also, of which I have found quite good indications, but I am getting too old to go into the hills alone.
William John Roydhouse was of a very active and sanguine nature, and one of the most pleasant tempered and amiable of men, making friends everywhere.
Sometime after writing his letter, he suffered a paralytic seizure, losing the power of speech and the use of his right arm and leg. He was cared for in the Victorian ward at Wellington Hospital, where he was a great favourite with the staff and other patients, owing to his unbreakable spirit.
He died on July 6th, 1908 at the age of 77 years.
