Mr Knight, also a photographer, writer and artist, died in 2008 aged 97, leaving thousands of collectables stacked floor to ceiling in his ramshackle Broad Bay home.
The last part of his collection will be auctioned at Hayward's Auction House tomorrow.
Hayward's co-proprietor Kevin Hayward said there had been strong interest in the auction, including from institutions such as the Hocken Library.
What was on offer represented the ''rump'' of Mr Knight's library, a sizeable collection of his own art and the remnants of his photography collection.
''I don't think you will see another collection of photographs of early Dunedin, early Otago, like it. There is just hundreds of them.''
Previously, parts of his collection had been auctioned off in Australia and other items had been acquired by the Hocken Library and Te Papa.
''So what we were instructed to do was to go through what was left in the house and ... get what we could salvage ... before the place was bulldozed.''
What they recovered were only the remnants, which showed just how large his collection had been.
