AI summary

The Official Cash Rate (OCR), set by the Reserve Bank (RBNZ), is a key tool for managing New Zealand's inflation. It's the interest rate at which the RBNZ lends to banks, directly influencing consumer mortgage and savings rates.

Raising the OCR cools the economy to fight inflation but can risk a recession. For homeowners, a practical strategy to manage fluctuating rates is interest rate averaging—splitting a mortgage into several portions with different fixed-term lengths to provide more certainty.
