New Zealand's ?economic recovery has been delayed but not derailed, ?Finance Minister Nicola Willis said on Thursday after the Iran conflict ?lifted fuel costs and ?dented business and consumer sentiment. Willis said Treasury's best-case scenario ?has ?inflation at 3.9% in the current fiscal year ending ?June 30 if oil averages $110 a barrel. A worst-case path of oil at $180 could push inflation to 7.4%, though she called that highly ?unlikely.
