The PLI is not a city cost/m² rate, current escalation series or tender estimate.
Direct answer
For early office construction cost planning in Avondale, 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 Avondale 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 Avondale market basket or current office tenders. GeoNames 2193703 records the locality at -36.8833, 174.7000, with snapshot population 26,450. That ranks Avondale 33 of 50 listed places, while New Lynn is the nearest listed peer at about 3 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.

| 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 Avondale adjustment | Not asserted | Replace with current local comparable evidence |
| Result status | Screening normalization | Not a budget, quote or tender estimate |
