Demand for New Zealand inflation-linked product is bringing the New Zealand government closer to issuing in this format for the first time in more than 10 years, with an announcement possibly coming as early as May 20 when the national budget is released. The news comes after Transpower Finance (Transpower) (AA/Aa3) launched New Zealand's first corporate inflation-linked bond on April 19, with a minimum size of NZ$75 million (US$53.3 million).
