WELLINGTON, May 23 (Reuters) - New Zealand's central bank governor, Adrian Orr, said on Thursday that while inflation was coming down it was disappointing how stubborn the domestic component of inflation remained to moving lower.

"The biggest risk we run is that we don't get inflation low and stable," Orr told New Zealand radio station NewstalkZB. (Reporting by Lucy Craymer; Editing by Leslie Adler)
