"Economic activity in New Zealand has picked up over recent months. However, the road ahead remains uncertain. As we outlined in our February Monetary Policy Statement, economic recovery is patchy, and ongoing uncertainty is expected to constrain business investment and household spending growth.
"Given the uncertainties ahead, it is appropriate to retain some restrictions on the dividends that banks can pay."
Bascand said the 50 per cent restriction would remain in place until July 1 next year, at which point it planned to lift the restrictions entirely.
The Reserve Bank has written to the banks to inform them of the decision while asking that the banks be prudent in determining how much they pay to shareholders.
"We have delayed the implementation timetable of the capital review twice over the course of last year to allow banks the regulatory relief needed to support their customers. As economic conditions improve, building strong capital buffers needs to be prioritised."
Higher capital requirements for the banks were meant to start coming into force in July last year but have been delayed until July next year.
