North has made two further changes to its list following the end of the NAB AFL Trade Period last week.

Defenders Brad McKenzie and Joel Tippett have been advised their contracts will not be renewed for next season.

GM Football Cameron Joyce praised the pair for their professionalism since arriving at Arden Street.

"These decisions are always tough," Joyce said.

"Both Brad and Joel have been great contributors during their time with us and we sincerely wish them all the best. Hopefully they can continue their AFL careers because both are very capable players."

McKenzie was North's first selection in the 2011 Draft at pick 18, and played 37 games for the Roos including a career high 14 in 2016.

Tippett was picked up in the 2013 Rookie Draft with North's 8th selection and managed 7 games with the club.

North recently welcomed Nathan Hrovat, Marley Williams and Paul Ahern to the club and has picks 11, 32, 33 and 87 in the upcoming 2016 NAB AFL Draft.
