A mortgage adviser is encouraging people to split their interest rates as the Reserve Bank starts to raise the Official Cash Rate.
Bank mortgage rates are expected to start rising soon to reflect an increase of 0.25 of a percentage point in the OCR on Thursday, to 2.75%. It was the first rise since July 2007.
Mortgage adviser John Bolton says people should not panic and rush into a wholly fixed rate mortgage because that will push up rates in the long-term.
He says a 0.25 percentage point increase is not going to make a marked difference in people's ability to afford their mortgage.
While rates will rise, Mr Bolton says he believes they will still stay relatively low.
