64. Implementation---(1) The contents of the pay equity determination
 shall be incorporated, in accordance with this section, into the award
 or agreement which is in force at the time of the making of the
 Arbitration Commission's decision on the implementation of the pay
 equity determination.

   (2) The contents of the pay equity determination shall be so
 incorporated as from the later of---

         implementation of the pay equity determination; or
   (b) The date of expiry of the award or agreement that was in force at
         the time when the pay equity claim was made.

   (3) The Arbitration Commission shall, of its own volition,---
   (a) Incorporate the contents of the pay equity determination into the
         award or agreement by including in the award or agreement a
         schedule of supplementary pay equity payments; and

         agreement and the schedule of supplementary pay equity payments.

   (4) The Arbitration Commission shall provide for the supplementary pay
 equity payments to be implemented over a period of 3 years unless the
 Arbitration Commission determines that either a shorter or longer period
 is warranted.

   (5) In deciding whether to reduce or extend the period of 3 years, the

 expeditiously as is practicable against the impact of the costs of the
 pay equity adjustment---

         Zealand; and
