North Melbourne has officially launched its 2012 membership campaign: Spirit - One and All.

"The one word that describes North Melbourne better than anything else is spirit," Chief Executive Officer Eugene Arocca said.

"This club, more than any has a culture that has been tested by adversity, hardened by courage and defined by spirit. Our supporters know it, feel it and understand it. It therefore seemed logical that our 2012 campaign highlights the significance of spirit to this club and its supporters."

A compelling membership video shot at Aegis Park was released on Sunday, featuring young gun Jack Ziebell.

"History has also proven that North people stick together - the phrase 'One and All' is in our club song because it has a meaning," Arocca added.

"This year, more than any, we want all of our supporters and members to come together under the banner 'Spirit - One and All'."

The campaign's creative also includes Andrew Swallow, Todd Goldstein, Daniel Wells, Brent Harvey, Drew Petrie and Scott Thompson.

North Melbourne coach Brad Scott says the club's unrivalled spirit has been critical in its history of success.

"That spirit has been an integral ingredient over many decades at North Melbourne and our players, coaches and staff have embraced it, but just as importantly, so too have our supporters."
