N.Z. PORTS REOPEN, BUT FURTHER CLOSURES POSSIBLE Harbour workers returned to work this morning after a strike in support of pay claims closed New Zealand's 15 ports for 24 hours yesterday. But the Harbour Workers Union told reporters the pay dispute is not settled and the union's national executive will meet here tomorrow to decide its next moves. "Obviously we will be considering further industrial action," Union secretary Ross Wilson said in a radio interview. The union rejects employers offers of a 7.5 pct pay rise over 15 months. It wants 7.0 pct over 12 months.
