Barbara McCaul in “McCaul Family Scotland” (first compiled in 1991 and updated to 2002) writes that Malcolm’s father:
… left his wife and children in Wellington to go to Australia to seek a better job. He did not return to New Zealand. His two elder children Enid and Graeme helped their mother bring up the younger children. His son George, and possibly Graeme too, visited him (in the 1920's) in Australia.

Brian’s (nzolivers.com) sister, Helen Oliver writes:
Granddad [Malcolm Graeme Cox McCaul] rowed with the Wellington Rowing Association as a young man. I remember he wore those stiff collars with the pieces sticking up all the time and they always dressed for dinner. I used to go to dinner at the Hotel with him after I was married as well, and we use to have French Champagne but it was too dry and bitter for moi! Lovely memories.

Peter Horneman Memories
Peter’s mother, Cora Horneman (nee Clark), was the sister to Brian’s (nzolivers.com) grandmother, Kathleen Rita McCaul (nee Clark). In a visit to Peter in Christchurch by Brian in May 2017, Peter said:
Uncle Graeme (M.G.C. McCaul) used public transport and never owned a motor vehicle. Brian recalled that he was told that his grandfather used to catch the first tram from Seatoun into town and catch the last tram home. If he missed that, he would walk home.
Peter recalled that while he worked in the Chief Post Office, in Featherstone Street, Uncle Graeme would come upstairs to collect any mail not in the box. M.G.C. McCaul was a very properly dressed gentleman - collar and tie. Peter would see him collect the mail but kept a low profile so that fellow staff did not realise that Peter knew him. Staff kept wondering who the gentleman was. Most businesses would send staff to collect the mail however, M.G.C. would collect it himself.
M.G.C.’s office was near the railway station and near the Waterloo Hotel. Peter said the building is not there now. Peter thinks a petrol station is there now. The company was Philips and Pike [Commission Merchants and Manufacturers Agents, wine and spirits importer] and was near the old Waterloo Hotel on Waterloo Quay in Wellington. Brian remembered silver service family dinners at the Waterloo Hotel hosted by his grandfather.
Peter said they hosted Uncle Graeme’s 90th birthday party at their home in Ngaio, Wellington. Brian on his laptop showed Peter scans of photos of this occasion. It was fascinating to realise, in one of the photos, was a painting clearly visible hanging on the wall of Peter and Brian’s ancestor, Bothilde Bodil Birgita Riegels [born 1752 at Søllestedgaard, Lolland Municipality, Zealand, Denmark] [Brian’s 5 times great-grandmother]. Brian had a photo of this painting for just over 44 years and did not realise the significance or family connection!

Location of plaque from Karori Cemetery records found in March 2022:
Area 12, Block BC, Row 12, Plot 005.
In loving memory Kathleen Rita beloved wife of Malcolm Graeme Cox McCAUL
b 2 Sep 1891 d 13 Jan 1945. And Malcolm Graeme Cox McCAUL b 1 Apr 1883 d 23 Nov 1975.

On the 5th April 2022, Brian of nzolivers counted the rows to determine a better reference. The plaque is located behind the crematorium in the brick archway. It is on the left-hand side (known as Niche Wall A), with that wall labelled with an "A" at the very bottom. The exact location on that wall is:
The 12th across from the left (out of 18 across), and then
The 5th down from the top
Starting from the top left, and counting this works out to be the 84th plaque on that wall “A”.

M Graeme C McCaul here is not only interned with his wife, but with his mother, Elizabeth. A reply, in an email dated 6 April 2022, to a further follow-up by Brian with the Business Support Officer, Cemetery & Crematorium Wellington City Council reads:
“I have checked the records for DIV A location 84 [and] I can confirm all 3 ashes were interred into this niche”.
“The urns they used to use were a lot smaller, they were normally the tin urns which in those days you could [place] 3 tin urns into one niche”.
