European stocks .STOXX had also nudged higher the day before with the European Central Bank seen cutting rates by 10 basis points at its policy meeting on Thursday.
But with central bank easing no longer a fresh theme, market gains were limited.

The New Zealand dollar NZD=D4 slipped 0.4% to $0.6731, pressured in part by news the Reserve Bank of New Zealand (RBNZ) was taking a fresh look at unconventional monetary policy strategies, with interest rates already at a record low of 1.5%.
