Coming in late to this, but for future reference The Friends of Linwood Cemetery Trust have done a considerable amount of photography of graves/plots over the years and have been for years trying to work out ways to get them accessible without much luck. They are backed up on harddrives. Brick walls with Govt organisations and as you can imagine not largely funded and only run by a handful of volunteers now, getting them online and maintaining that is almost impossible. Their website appears to have a warning when it opens but it's not dangerous to ignore as far as i can see, I've opened it a couple of times - and I know it was being work on the back end properly while I was more fully involved with the trust.
https://www.linwoodcemetery.org.nzI am a Lifelong member however live in Auckland and don't have access to the photographs that have been taken over the years. The former secretary Alexandra who did an immense amount of work in relation to naming and processing them moved back to England in 2016 however did keep her hand in it for a while but not now. The facebook page is
https://www.facebook.com/TheFriendsOfLinwoodCemetery - if you cannot locate images elsewhere.
The membership was near critical level last I heard as the members have dwindled in the trust. Most are elderly with a couple of 'younger' ones thrown in and answers may not be immediate due to their family commitments, but i keep an eye as admin on the page (for now) and i can try and move the query along if need be.
