Despite the retreat from yesterday's New Zealand morning high at 87.45, a firm breach of support at 85.86 is needed to signal the correction from the 14-year low made last week at 84.82 has ended, yield weakness to 85.40/50 and then re-test of said support, otherwise, further choppy trading is in store.  
  
On the upside, above 86.75/80 would bring another corrective rise to aforesaid resistance at 87.45 but 88.01 (previous support) should remain intact.
