Raue, who has been a Greens Party member for seven years, previously wrote a similar article in 2012 campaigning to allow bestiality.
However, Raue strongly claims he was joking and that it is not his honest view.
Speaking to Daily Mail Australia, Raue said he doesn't stand by his comments as he "never really meant them" and said doesn't want necrophilia legalised.
"I have no interest in legalising necrophilia... Time wasted talking about joke articles I wrote as a student is an insult to the people of NSW."
Raue explained his current campaign will focus on solving the housing crisis, reversing all privatisation of public transport, early childhood education, taxing the rich and tackling the war on drugs.
The article has sparked outrage among NSW politicians.
A Macquarie Street MP believes the Greens should "do the right thing and disendorse him".
