A man accused of stabbing Morgan Huxley to death in his Sydney unit has pleaded not guilty to murder.

Daniel Jack Kelsall was charged in October last year with murdering Mr Huxley, about a month after the 31-year-old was found with multiple stab wounds in his Neutral Bay apartment in the early morning.

He died of his wounds at Royal North Shore Hospital.

Kelsall, 21, appeared briefly via audio video link at the NSW Supreme Court on Friday where he pleaded not guilty to the murder.

He also pleaded not guilty to the additional charges of indecent assault, larceny and entering a home.

He is due to face trial from March 2 next year with the case expected to run for four weeks.
