Analysts are divided on whether the OCR will be cut.
Three leading economists have offered varying predictions.
Deutsche Bank chief economist Darren Gibbs thinks it will be a close call, but a cut is more likely than not.
GoldmanSachs JB Were investment research director Shamubeel Eaqub expects the OCR to stay steady, but says chances of a cut are near even.
Bank of New Zealand head of research Stephen Toplis says the Reserve Bank will wait until September to make a reduction.
