LANGE PREDICTS N.Z. INFLATION TO FALL TO 8-10 PCT New Zealand's inflation rate could fall to eight pct in the coming year, Prime Minister David Lange said. He said forecasts to be released soon by research groups would predict a rate of around eight or nine pct in the 12 months to the end of March 1988, against 18.2 pct in calendar 1986. "I predict it will be something between eight and 10 per cent," he told a news conference. Lange would not name the forecasting groups.
