The Pietermaritzburg-born player has been a regular for Abafana Be'sithende, scoring four goals in all competitions, including a brace against Bidvest Wits in the Telkom KnockOut.
Pirates Public Relations Officer Mickey Modisane could not deny or confirm to Goal whether they are interested in signing the 22-year-old striker.
"This exercise is done at another level. I am not in a position to reveal such information," Modisane told Goal.
Two Pirates players William Twala and Manti Moholo recently joined Arrows both on loan, a deal that fueled rumours linking Ntuli with The Buccaneers.
