Prime Minister John Key has acknowledged the high currency is tough for exporters, but said intervention by the Reserve Bank was unlikely to be successful because it had not worked overseas and the New Zealand economy continued to be seen as more attractive than the US economy.
He said he did not want to risk taxpayers' money on intervention when there was no certainty of success.
Markets continued to re-rate the US economy, making New Zealand relatively more attractive, he said.
Speaking on TV3's Firstline this morning, Key said any decision on intervention was ultimately a matter for the Reserve Bank.
"But I think you need to appreciate that what's happening here is a re-rating of the US economy and the various instruments that reflect the health and well-being of the US economy," Key said.
