There's division among economists regarding how soon the Reserve Bank should start raising the Official Cash Rate. 

Many now expect the bank to bring forward OCR hikes, with ANZ forecasting three before the election.

Kerr says more persistent forms of inflation, like wage and rental inflation, are quite benign at the moment.
