Police initially jointly charged 39-year-old Clarke and 40-year-old Yorke with murdering Oakes.
The pair now also face joint charges, laid last week, that include burglary, kidnapping, and disfiguring with intent to cause grievous bodily harm, which they have now denied.
The latter two charges relate to allegations the pair unlawfully detained and disfigured another man in Te Puke between January 1 and March 17.
Watson, 24, is jointly accused of murder and burglary.
Three other men, also jointly charged with burglary, appeared in court after the three murder defendants.
Billyboy William Whare, 30, James Anderson, 29, and Jaye Wera Manley, 33, denied the burglary charge.
It relates to an allegation that the six men unlawfully entered an enclosed yard on Manoeka Rd in Te Puke on October 25.
All six defendants were remanded in custody.
