Divided opinions on how deeply the Reserve Bank will slash the Official Cash Rate this afternoon

Economists expect a cut to the current rate of three-percent - but are at odds over whether it will fall 25 or 50 basis points.

Some favour a gradual drop until there's more information - but others suggest we need to move the economy along.

ASB's Nick Tuffley expects there'll also be debate on the monetary committee - with disagreement over recent decisions.

He says what Governor Christian Hawkesby decides will be critical - because his vote counts twice if members are split three versus three.
