Novakiella trituberculosa is a species of South Pacific orb-weaver spiders, found in Australia and New Zealand.
N. trituberculosa was originally placed in the now obsolete genus Epeira as E. tri-tuberculata. Carl Friedrich Roewer temporarily moved it to Araneus while dissolving this "catch-all" taxon, and it was later placed into its own genus, Novakia, later renamed to Novakiella.
The female is recorded at 9mm in length whereas the male is 7.2mm.
This species is native to New Zealand and Australia.
Under the New Zealand Threat Classification System, this species is listed as "Not Threatened" with the qualifier of "Secure Overseas".
