N.J. Stat. § 54:5-22
When an assessment for benefits for municipal improvements is payable in installments by virtue of any law, ordinance or resolution and under the terms of that law, ordinance or resolution, or of any other law, the whole amount or unpaid balances of the assessment has become due and payable by reason of a default in the payment of any of the installments, or in the payment of any other municipal lien, the governing body of the municipality, or the board or body having charge of its finances, may by resolution determine that any subsequent installments which would not yet have become due except for the default shall be considered as not in default, and may by such resolution direct the collector to withhold from any tax sale the subsequent installments not yet due and offer the premises for sale only under the installments or other municipal liens which may be actually in default. The sale shall then be made subject to the lien of the installments not yet due.
