Direct answer

For early retail construction cost planning in Richmond, the World Bank ICP reports a 2021 New Zealand construction price-level index of 362.0, with the world equal to 100. This is a national comparison—not a Richmond NZD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across New Zealand in 2021; it does not measure a Richmond market basket or current retail tenders. GeoNames 2183472 records the locality at -41.3333, 173.1833, with snapshot population 19,950. That ranks Richmond 44 of 50 listed places, while Stoke is the nearest listed peer at about 5 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

What does the 362.0 construction index mean?

The World Bank ICP 2021 construction PLI for New Zealand is 362.0, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that retail work in Richmond costs 3.620 times a current world rate.

Which Richmond inputs are known?

The reproducible locality point is -41.3333, 173.1833 (GeoNames 2183472). Its snapshot population is 19,950, ranked 44 of 50 listed places; GeoNames classifies it as a first-order administrative seat in administrative area TAS. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Richmond retail project, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works. Use a consistent gross-floor-area basis and record the following before reliance.

Estimate field	Screening record	Project requirement
National context	ICP 2021 PLI 362.0	Retain only as dated cross-country context
Local NZD/m² rate	Not supplied	Current comparable with named source and base date
Area and scope	Gross floor area; scope unresolved	Measurement standard, specification and procurement route
Additions	Not supplied	Taxes, fees, site work, contingency and escalation
Review	Automated source and arithmetic QA	Qualified local cost review

Price-level normalization worksheet

For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (362.0 ÷ P). At P = 100 the dimensionless ratio is 3.620; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.

Input	Recorded value	Release condition
Target national PLI	362.0 (World = 100, 2021)	Screening context only
Reference construction PLI P	User-supplied from the same ICP classification/year	Must match reference rate country
Validated reference rate R	User-supplied	Named source, currency, date, area and scope
Local Richmond adjustment	Not asserted	Replace with current local comparable evidence
Result status	Screening normalization	Not a budget, quote or tender estimate

Frequently asked questions

Does the 362.0 index give a retail cost per m² for Richmond?

No. 362.0 is the World Bank ICP 2021 national construction price-level index for New Zealand, with the world equal to 100. It is a cross-country screening statistic, not a Richmond NZD/m² rate, escalation index, quote or tender estimate.

How should a Richmond retail estimate replace this screening benchmark?

Collect current Richmond comparables on a consistent gross-floor-area basis, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
