What the Data Shows
New Zealand CPI contributions are measured by selected category contributions to annual inflation in the March 2026 quarter. The data shows housing at 0.991 percentage points, food at 0.747 points, transport at 0.493 points and electricity at 0.338 points. Housing and food together contributed about 1.738 percentage points to the annual CPI rise. Electricity is an item-level contribution within housing and household utilities, so it should not be added separately to the housing group.

Data notes & caveats
Contribution values are percentage points of annual CPI inflation. Electricity is item-level and sits within housing and household utilities, so it should not be added to the housing group.
Methodology
Use Stats NZ annual CPI contributions for the March 2026 quarter. Electricity contribution is calculated from the reported 10.9% share of the 3.1% annual CPI rise: 3.1 × 10.9%.
Source consistency notes
Category contributions and annual CPI come from the same Stats NZ release; the electricity point contribution is a transparent calculation from the same release.
