N.Y.C. Admin. Code § 11-117: § 11-117 Renewal of bond.

If at any time during the continuance in office of the city collector or deputy collectors the comptroller or commissioner of finance shall deem any surety of them to be insufficient, he or she may require the city collector or deputy collectors to enter into a new bond to be approved in like manner as prescribed in section 11-115 of this chapter, within such time as the comptroller may direct, not being less than ten days after requiring such new bond to be given. In case of the neglect or refusal of any such officer to furnish such bond within the time so directed, the comptroller or commissioner of finance may declare his or her office vacant.
