2006 New York Code - Duties Of Treasurer.

 
    § 69. Duties  of  treasurer.  The  treasurer  shall  demand,  collect,
  receive and have the care and custody of and shall disburse  all  moneys
  belonging  to  or  due  the  city from every source, except as otherwise
  provided by law. All moneys of the city received by the treasurer  shall
  be  deposited  and secured by him daily in such depositaries as shall be
  designated by the board of estimate  and  apportionment  in  the  manner
  provided  by  section ten of the general municipal law. The interest, if
  any, on all deposits shall be the property of  the  city  and  shall  be
  accounted  for  and  credited to the appropriate fund. No money shall be
  drawn from a city depository except on checks signed  by  the  treasurer
  and  countersigned  by  the  comptroller  and made payable to the person
  entitled to receive the same. He shall at no time permit any fund to  be
  overdrawn,  nor draw upon one fund to pay a claim chargeable to another.
  No money shall be paid out  by  him  except  upon  the  warrant  of  the
  comptroller.    He  shall  render  to the comptroller at the end of each
  day's business a detailed statement of all moneys received and paid  out
  by  him. He shall perform such other duties, as may from time to time be
  prescribed  by  law,  or  by  ordinance  of  the  common  council,   not
  inconsistent  with  the  provisions  of this chapter, or the laws of the
  state.  By  resolution  duly  adopted,  the  common  council  or   other
  legislative  body of the city, may determine to enter into a contract to
  provide for the deposit of the periodic payroll of the city in a bank or
  trust company for disbursal by  it  in  accordance  with  provisions  of
  section ninety-six-b of the banking law.
