A prediction the Reserve Bank is unlikely to cut the Official Cash Rate, despite inflation easing.

Inflation increased 6.7 percent in the year to March, dipping from 7.2 percent December.

Westpac Senior Economist Michael Gordon says it'll be down to easing international pressures on things like shipping prices.

He thinks the Reserve Bank won't yet relax the OCR yet, which is now sitting on 5.25.

"I still think they'll be keen to signal their vigilance against inflation, they've done a lot of work already and it just needs to take some time for high interest rates to have their impact on things."
