    Simple explanation

    Actual profit

    Technical context

    Test this point against Final budget, the current feasibility version and written input from Developer. Separate verified facts, professional opinion and assumptions.

    Why it matters: This check can change yield, consent pathway, acquisition terms, funding, cost, programme or exit strategy. It must be resolved before the developer relies on what to repeat.

    Prerequisites

    • Final budget is current and its source/date are recorded.
    • The project objective, feasibility version and decision deadline are clear.
    • Developer has a focused brief where professional confirmation is required.

    Checks

    • Does Final budget directly support the conclusion?
    • Which information is verified, assumed, missing, superseded or contradictory?
    • Has the feasibility, programme, risk register and decision register been updated?

    Evidence to save

    • Final budget
    • Written Developer response or a recorded reason it is not required
    • Dated feasibility/risk/decision update

    Hold point

    Do not waive a condition, instruct design/work, commit funding, lodge, purchase, settle or represent the conclusion as confirmed until the authorised decision-maker has the required evidence and advice.

    Stop or escalate when

    • The source is missing, old, inconsistent or outside the reviewer's scope.
    • The check changes yield, approval pathway, funding, legal rights, tax, safety or a material cost/programme assumption.
    • A deadline is approaching and the responsible professional has not confirmed the position.

Developer go / no-go control

Decision gates before the next commitment

A gate records whether evidence supports a commercial decision. It does not replace advice or predict an authority, lender, purchaser or market outcome.

Before the next material commitment

Decision: Proceed, pause, obtain evidence, or escalate

Minimum evidence

  • • Current source documents and professional responses
  • • Versioned feasibility, risk and programme update
  • • Named owner and deadline for every unresolved dependency

Update before deciding

  • • Cost and contingency
  • • Time and holding/finance effect
  • • Yield, value, consent and exit effect

Stop / escalate when

  • • A material conclusion is still an assumption
  • • Sources conflict or are out of date
  • • The authorised decision-maker cannot see the downside consequence

What this stage means

  • Post-completion review is the part of the project where the developer turns an idea into a checked decision, not a guess.
  • The stage should connect market demand, planning rules, legal constraints, design, cost, funding, time, risk, and exit strategy.
  • For Auckland residential development, the answer is site-specific. The same idea can be low risk on one site and unworkable on the next because of zoning, overlays, title interests, services, slope, flooding, neighbours, or finance.

Why this stage matters

  • Early mistakes become expensive because land, design, consultants, holding costs, consent fees, and finance costs continue even when the project is paused.
  • The developer needs written evidence for lenders, consultants, lawyers, valuers, builders, purchasers, and future dispute protection.
  • This stage usually needs verification from Inland Revenue property guidance, Relevant professional advice before the developer treats the conclusion as reliable.

Step-by-step guide

  1. 1Define the decision needed at the end of this stage and the date it is needed by.
  2. 2Gather the stage documents: Final budget, Final feasibility, Sales results, Defect log, and the remaining stage records.
  3. 3Read the documents once for understanding, then again to list unknowns, risks, contradictions, missing evidence, and professional questions.
  4. 4Ask the responsible professionals to confirm the critical points: Developer, Accountant, Project manager, QS.
  5. 5Update the feasibility, programme, risk register, and decision register with source references and dates.
  6. 6Decide whether to proceed, pause, redesign, renegotiate, add conditions, seek more advice, or abandon the option.
  7. 7Save the evidence in a dated folder and write a short stage closeout note explaining what was decided and why.

What the developer must do

  • Write down the development objective for post-completion review in one clear paragraph: build-to-sell, build-to-rent, retain one dwelling, subdivide, renovate, or staged development.
  • Open the current feasibility, programme, decision register, risk register, and due diligence folder before making new commitments.
  • Collect the documents needed for this stage: Final budget, Final feasibility, Sales results, Defect log, Lessons learned, Archive checklist.
  • Send focused questions to the right people: Developer, Accountant, Project manager, QS, Agent, Builder, Lender.
  • Record assumptions separately from verified facts so the feasibility does not look more certain than it really is.
  • Update cost, time, consent, finance, and sales assumptions immediately after receiving new information.
  • Escalate anything that changes yield, sale price, cost, timing, consent pathway, title, funding, or settlement risk.

Verification

Source / where to check

Use current official information and the controlled documents for the actual project.

Inland Revenue property guidance

Use IRD property guidance for tax topics such as income tax, GST, rental income, property sales, and entity records. Confirm project-specific treatment with an accountant or tax adviser.

Relevant professional advice

Planner, surveyor, architect, engineer, quantity surveyor, lawyer, accountant, lender, valuer, real estate agent, and other project specialists must confirm site-specific decisions.

Project-specific consented documents and professional advice override generic guidance.

Common mistakes

  • Treating an agent comment, generic online rule, or old document as verified site-specific advice.
  • Forgetting to update the feasibility after design, consent, finance, or market information changes.
  • Not allowing enough contingency, professional fees, council fees, finance costs, holding costs, and time risk.
  • Failing to keep written records of who confirmed what and when.
  • Using post-completion review to push ahead even when the red flags show the project should pause.

Common risks

  • Yield reduces after proper planning, engineering, title, or infrastructure review.
  • Costs increase after QS, builder, civil, geotechnical, demolition, asbestos, or consent information is received.
  • Programme moves out because consultant inputs, council RFIs, neighbour issues, finance, title, or construction sequencing take longer than assumed.
  • Funding or sales assumptions change before the project reaches settlement.
  • The developer relies on unverified information and loses negotiating power or misses a due diligence deadline.

Common costs

  • Professional fees for planner, architect/designer, surveyor, engineer, QS, lawyer, accountant, valuer, and lender reports.
  • Council fees, consent fees, development contribution estimates, engineering approvals, infrastructure checks, and inspection/monitoring costs where relevant.
  • Design revisions, reports, investigations, demolition/asbestos work, service location, geotechnical testing, and valuation updates.
  • Holding costs such as interest, rates, insurance, utilities, temporary maintenance, and security.
  • Contingency for unverified conditions until the relevant professional confirms them.

Quotes and fee proposals to obtain

  • Obtain written fee proposals or quotations from the relevant stage professionals: Developer, Accountant, Project manager, QS, Agent, Builder, Lender.
  • Issue the same current documents and a clear scope to each party so prices, exclusions, assumptions, deliverables, lead times, and programme can be compared.
  • Identify council, authority, investigation, testing, design, construction, monitoring, and close-out charges that may sit outside a consultant or contractor quote.
  • Record every provisional sum, estimate, exclusion, expiry date, dependency, and unverified allowance in the Quote Register and feasibility.
  • Do not approve an appointment or purchase order until scope ownership, evidence required, payment terms, variation process, insurance or competency checks, and completion deliverables are understood.

Common delays

  • Waiting for property file, LIM, title instruments, survey information, consultant reports, or council responses.
  • Design changes caused by planning controls, infrastructure constraints, engineering findings, budget pressure, or market feedback.
  • Lender, valuer, lawyer, or purchaser conditions not being satisfied on time.
  • Council RFI responses needing more consultant work than expected.
  • Construction or subdivision closeout documents not matching settlement or sales deadlines.

Common consultant questions

  • For Post-completion review, what are the three highest risks that could change cost, time, yield, or approval pathway?
  • Which parts of your advice are confirmed, which are assumptions, and which require another professional to confirm?
  • What documents did you rely on, and are any documents missing, outdated, superseded, or inconsistent?
  • What decision does the developer need to make now, and what should wait until more information is available?
  • What wording should go into the decision register, consultant meeting minutes, or lender/client update?

Red flags

  • A professional says the issue is outside their scope and no one else has been asked to confirm it.
  • The feasibility only works if optimistic sale prices, low construction costs, fast consent, low interest, and no delays all happen together.
  • A title, planning, flooding, geotechnical, access, service, or covenant issue may prevent the intended yield.
  • A seller, agent, builder, or consultant pressures the developer to waive due diligence before core checks are complete.
  • The project file has no written evidence for a major decision.

When to stop and get professional advice

  • Stop and get professional advice when title, easements, covenants, unit title, cross lease, or subdivision matters affect the proposal.
  • Stop and get professional advice when zoning, overlays, activity status, notification, infrastructure capacity, flooding, geotechnical, contamination, or heritage could affect yield.
  • Stop and get professional advice when GST, income tax, entity structure, lending, guarantees, or sale contract terms affect the decision.
  • Stop and get professional advice when the developer is about to sign, waive a condition, lodge consent, start work, approve a variation, accept practical completion, or settle.

Decisions that must be made

  • What to repeat
  • What to change
  • Which consultants/builders to use again
  • How future feasibility assumptions should change

Evidence to save

  • Dated source documents and consultant advice.
  • Feasibility version showing the assumptions used at the time of decision.
  • Risk register and decision register entries.
  • Meeting notes, emails, marked-up plans, calculations, photos, and council/lender/consultant responses.
  • Clear note of who approved the next step and any conditions attached to that approval.

Beginner-friendly example

The developer learns that civil costs were under-allowed and increases early civil due diligence on the next project.
