Bank QS Reports in NZ — What the Quantity Surveyor Checks, What It Costs, and How to Pass First Time

Your lender will not advance construction funds on a handshake. For most NZ construction loans above the minor-works threshold, the bank appoints or requires a registered quantity surveyor to verify the project before the first drawdown — and at every drawdown after that. Here is what that QS will check, what the reports cost, and how to arrive with a file that passes first time.

What an Initial QS Report and a Drawdown Report actually contain
What banks require, who can sign, and the market rates for each report
The document pack that gets a project through QS review without re-work delays

Quick answer: NZ banks lending on construction typically require two kinds of quantity surveyor report: an Initial Report before the loan is advanced (a detailed cost estimate testing whether the contract sum can actually complete the works, plus a review of the construction contract, the programme, the consents, and the consultants' professional indemnity cover) and Drawdown Reports through the build (verifying claimed progress before each advance). The reports must be signed by a Registered Quantity Surveyor — NZIQS membership at MNZIQS grade or above — under the NZIQS Construction Financing Reports guidance. Market rates run around $3,900 excl GST for an Initial Report and around $900 excl GST per Drawdown Report. Most first-time failures are document failures, not cost failures: an unexecuted contract, a programme without dates, or a consent condition nobody closed out.

Why the bank wants a QS between you and the loan

A construction loan is advanced progressively against work completed. The bank's exposure is the gap between what it has advanced and what the part-built asset would fetch if the project stalled. The QS report is how the bank measures that gap. The Initial Report tests the project before any funds move; the Drawdown Reports test each claim before each advance.

For the borrower — owner, developer, or builder on a turnkey — the QS report is not an adversary. It is a gate. Projects that arrive at the gate with a complete, consistent document pack pass in days. Projects that arrive with a contract sum that does not reconcile to the drawings, or a programme that does not name practical completion, sit in correspondence for weeks while interest accrues on the land advance.

What the Initial QS Report contains

Under the NZIQS Construction Financing Reports guidance note, the financier's brief asks the QS to prepare and verify, at minimum:

A detailed construction cost estimate for the development, tested against the contract sum — the central question is whether the contracted figure is sufficient to complete the works, not whether it is cheap
A review of the executed construction contract — form of contract, contract sum, retentions and payment terms, and whether the agreement as signed is suitable for the project
The construction programme — with clear commencement and practical completion dates the drawdown schedule can hang off
Consents — confirmation the building consent (and resource consent where applicable) has been issued, including the council's mandatory inspection stages and any engineer-review conditions
Consultants' professional indemnity insurance — confirmation the architect, structural engineer, civil and services engineers, geotechnical engineer, and any engineer to the contract hold current PI policies with adequate cover
Contingency adequacy — whether the allowances for provisional sums, PC sums, and escalation are realistic for the project's risk profile

The report typically closes with a funding-table recommendation: the cost to complete, the contingency the bank should hold, and any conditions to clear before first advance.

What Drawdown Reports check

Each progress claim triggers a Drawdown Report before the bank advances against it. The QS verifies:

The work claimed is in place on site, at the percentage claimed
The claim reconciles to the contract payment schedule and the previous certificate
Variations are documented and the cost-to-complete still fits the remaining facility
Retentions have been deducted correctly
The programme position — whether practical completion is still achievable inside the facility term

A claim that fails any of these comes back to the borrower as a query, and the advance waits. On a typical 10-14 drawdown residential development, two or three stalled drawdowns can add a month of interest cost.

Who can sign, and what the reports cost

The reports require a Registered Quantity Surveyor — NZIQS membership at MNZIQS grade or above. This is a lender requirement, not a guideline: an estimate from a builder, an architect, or an unregistered estimator does not satisfy the brief, however accurate it is.

Market rates in the current NZ market:

| Report | Typical market rate (excl GST) | When | |---|---|---| | Initial Report | ~$3,900 | Before loan advance | | Drawdown Report | ~$900 per report | Each progress claim | | Full programme (initial + 10-14 drawdowns) | $13,000-17,000 | Across the build |

Rates vary with project size, complexity, and region. The cost is borne by the borrower and is small against the facility — the real cost variable is delay, not fees.

How to pass first time — the document pack

Trueworks is not a registered QS practice and does not issue bank reports. What we do, for builders and owners heading into a lending review, is get the document pack tight before the registered QS opens it. The pack that passes first time:

The executed contract — signed by both parties, with the contract sum, retentions, and payment terms consistent with the tender
The stamped consent set — with the drawing revisions on the contract matching the revisions the council stamped
A dated programme — commencement, practical completion, and the claim cycle aligned to the drawdown schedule
A reconciled cost breakdown — trade-by-trade, with provisional sums and PC sums separated and the contingency stated
The consultant schedule — each consultant named with PI insurer and expiry date
The variation register — even if empty at day one, the format the project will run on

A 30-minute reconciliation pass across these six items — does the contract sum match the breakdown, do the revisions match the consent, do the dates match the facility — removes the most common QS-review queries before they are asked.

Where the projects actually fail

Three patterns produce most first-review failures:

1. The contract-sum reconciliation gap. The tender breakdown was revised after acceptance, the contract was signed on the earlier figure, and the two no longer match. The QS cannot certify sufficiency against a moving number.

2. The consent-condition orphan. A resource-consent condition (a retaining-wall certification, an arborist sign-off, a stormwater connection approval) sits unclosed, and the cost of closing it is in nobody's breakdown.

3. The optimistic contingency. A renovation or steep-site project carrying a 2-3% contingency where the risk profile says 8-12%. The QS flags it, the bank holds more, and the borrower's equity requirement moves at the worst possible moment.

Each of these is a document fix at week zero and a funding problem at week six.

FAQ — bank QS reports in NZ

Q1: Does every construction loan need a QS report? No — small alteration loans below the lender's threshold (commonly in the low hundreds of thousands, varying by bank) may be advanced on a registered valuer's report alone. Above the threshold, and on virtually all development lending, the QS reporting regime applies.

Q2: Who appoints the QS — the bank or the borrower? The borrower typically engages and pays, but the QS acts for the lender and must be acceptable to the lender — in practice a Registered Quantity Surveyor (MNZIQS or above) from a practice the bank recognises.

Q3: What is the difference between an Initial Report and a feasibility estimate? A feasibility estimate tests whether a project is worth doing. The Initial Report tests whether the contracted figure can complete the works, against the executed contract and the consented drawings. It is a verification document, not a design tool.

Q4: Can the same QS who priced the job do the bank report? Generally no — the lender wants independence. A QS who prepared the builder's tender pricing has a conflict on the sufficiency question.

Q5: What happens if the Drawdown Report finds the cost-to-complete exceeds the remaining facility? The bank pauses advances until the gap is closed — by borrower equity, a facility variation, or a documented saving. This is the scenario the Initial Report's contingency recommendation exists to prevent.
