WELLINGTON, May 26 (Reuters) - The Reserve Bank of New Zealand (RBNZ) held its official cash rate (OCR) at 0.25% in a widely expected decision on Wednesday, following a regular policy meeting. The central bank also retained its large scale asset purchase (LSAP) programme at NZ$100 billion ($72.18 billion). The Funding for Lending Programme (FLP) operation was unchanged. Economists in a Reuters poll had unanimously expected the RBNZ to hold rates.
