North Melbourne have announced Jack Ziebell will retain the captaincy for the 2018 season after announcing their leadership group this morning. 

The 26-year-old will lead the Roos for a second straight season as Robbie Tarrant (vice captain), Shaun Higgins and Jamie Macmillan join him in the leadership group. 

Ziebell said 2017 had been a learning curve for him that allowed him to develop his leadership qualities both on and off the field. 

"I think we are very content and excited about the boys in our leadership group. There are plenty of young boys with leadership qualities too," said Ziebell, speaking at North's Arden St headquarters. 

"I've learnt a lot as a leader in the last 18 months. The start of last season was definitely a challenge, but the guys had really good resolve and that made my job easier."

Ziebell drew high praise from coach Brad Scott has he battled through injuries for much of 2017, leading to post-season surgery on a toe injury. 

“There were times throughout the season when we wanted to rest him, mainly to protect him from himself,” Scott said.

“Jack simply refused to lie down and pushed through a lot of the time at his own expense.”

North will possess the third-youngest list in the AFL in 2018 and North Melbourne will look to develop their younger leaders throughout the season, with an eye already on next year's leadership crop.
