Free Google Ads Audit New Zealand: A National Checklist

A free Google Ads audit for a New Zealand account should prove whether campaigns reach the regions, towns, service areas, and customers the business can serve; measure valuable actions; spend against a defined commercial objective; and send people to a page and offer that work after the click. Aotearoa New Zealand is not one uniform market. A nationwide retailer, an Auckland service company, a tourism operator, and a business serving rural or remote communities need different evidence.

Use this page as a practical starting point for a New Zealand Google Ads audit. Check account scope, regional reach, conversion quality, search demand, budgets, landing pages, GST and price context, and business results in that order. For a live first pass, the free Google Ads audit from adz.so can help organise supported account checks; the output is evidence for human review, not automatic permission to change a campaign.

What a New Zealand Google Ads audit should prove

The useful output is a short evidence record rather than a score detached from its assumptions:

• Scope: Which account, campaigns, networks, dates, reporting time zone, billing currency, and owners were reviewed?
• Reach: Is the campaign intended for New Zealand as a country, selected regions, cities, towns, postcodes, service radii, or a combination? Do settings and observed delivery agree?
• Intent: Is the business buying purchases, qualified leads, calls, bookings, applications, subscriptions, or another defined result?
• Measurement: Does each conversion represent a valuable action, and are browser, server, phone, CRM, and order events counted once?
• Economics: Are spend, revenue, margin, freight, returns, GST treatment, lead quality, sales lag, and capacity defined well enough to judge performance?
• Action: Which finding should be reviewed first, who owns it, and what evidence is still missing?

Stats NZ’s business demography information provides an annual snapshot of New Zealand businesses and includes regional and industry context. Public statistics can challenge the assumption that every part of New Zealand is commercially interchangeable, but they do not select an advertiser’s service area, customer, product mix, or bidding decision. Use them as context and use the account and business systems for the advertising decision.

Define the evidence before interpreting it

Write down the date range, account time zone, billing currency, conversion windows, attribution view, data freshness, and reporting owner. A campaign may serve several regions while the platform cuts the day at one account setting. An order may need freight, cancellations, and returns to mature; a lead may need qualification or a booking may need completion. These definitions are part of the result.

Use unknown or partial when a source is unavailable, delayed, privacy-limited, or outside the agreed scope. A region with no recorded conversion is not automatically a failed market. It may have low volume, a tracking defect, a long sales cycle, or no capacity. Preserve the distinction so the audit does not turn an evidence gap into an automatic optimisation.

Confirm the account, market, and New Zealand campaign boundary

An account name that says “New Zealand” does not define the intended reach. Write the boundary down before reading performance. A national retailer may deliver to cities but use different freight rules for rural addresses. A local service business may use a radius around a branch. A tourism advertiser may target people interested in a destination rather than people physically present there. A business serving Māori or bilingual audiences may need a distinct cultural, language, or service path that the account should not imply without operational support.

Record the customer or manager account ID, account time zone, billing currency, campaign status, network, date range, data freshness, and people authorised to approve a change. Map the relationship between:

• New Zealand-wide campaigns and campaigns for Auckland, Wellington, Christchurch, Hamilton, Tauranga, Dunedin, or other regional markets;
• region, city, town, postcode, radius, branch, depot, and service-area boundaries;
• national brand, non-brand, product, service, recruitment, tourism, and local campaigns;
• product availability, freight, appointment, opening-hour, phone-routing, and sales ownership;
• English or te reo Māori ad, keyword, landing-page, form, support, and conversion paths where applicable.

Do not infer service coverage from a region name alone. Compare the selected location with the actual delivery, licensing, appointment, or sales boundary. A postcode, territorial authority, region, urban area, and freight zone can be different units. If the business uses a postcode list or service map, preserve the exact inclusion and exclusion rule instead of translating it into a broad region target and assuming the result is equivalent.

Segment the account by business model

Keep evidence separated until the commercial outcome is clear:

1. Ecommerce and retail: reconcile orders with product availability, freight cost and time, GST treatment, discounts, cancellations, returns, and contribution. Gross order value in NZD is not automatically profit.
2. B2B and professional services: distinguish an enquiry or booked call from an accepted lead, opportunity, proposal, won account, and retained customer. Keep region, industry, sales stage, and cohort visible.
3. Trades and local services: define accepted postcodes, travel time, opening hours, call handling, appointment capacity, booked jobs, cancellations, and completed work.
4. Tourism and destination services: separate destination research, booking, arrival, cancellation, season, capacity, and domestic or international demand.
5. Agencies and manager accounts: keep client accounts, permissions, currencies, time zones, conversion definitions, and data owners separate. A manager average can hide a regional, language, or import problem.

Audit regional, location, and language reach

Google’s location guidance explains that campaigns can use countries, areas within a country, radii, and location groups, and that location targeting is based on multiple signals rather than perfect geographic accuracy. Review Google’s location-targeting documentation, advanced location options, and location and language settings when checking the account.

Compare settings with observed delivery:

• selected country, region, city, town, postcode, radius, or location group;
• included locations, exclusions, nearby-area behaviour, and the campaign level at which an exclusion applies;
• presence, interest, or both in the location option;
• overlap between national, regional, local, branch, and radius campaigns;
• location adjustments, separate budgets, feeds, landing pages, or phone routes and the dates they changed;
• impressions, clicks, cost, conversions, qualified outcomes, and revenue by geography where measures are trustworthy;
• freight, service, appointment, language, opening-hour, and sales-routing consistency for each area;
• whether destination interest, travel research, and physical presence are intentionally in or out of scope.

Do not use a national average to hide regional differences. Auckland, other urban markets, provincial towns, and remote areas can have different demand, delivery economics, service capacity, and data volume. A low-converting region may have weak demand, a tracking problem, a long sales lag, or no capacity. Before moving budget, verify the denominator, campaign scope, location option, conversion maturity, and business outcome.

Review conversions and search demand before judging performance

Google defines conversion tracking as measuring whether ad interactions lead to valuable actions such as sales, leads, calls, or downloads. Use the Google Ads conversion tracking definition and conversion measurement guidance as references, then verify the business record. Record each action’s source, owner, primary or secondary status, counting rule, value and currency, attribution, window, deduplication key, source freshness, and lag to a shipped, accepted, booked, completed, or retained outcome.

For ecommerce, reconcile orders with freight, GST, discounts, returns, and contribution. For lead generation, compare forms and calls with accepted leads, appointments, opportunities, and closed revenue. For local services, separate answered calls, booked jobs, completed work, cancellations, and postcode eligibility. For tourism or events, distinguish an enquiry or booking from arrival, completion, cancellation, and capacity. If an offline import is late or browser and server events can both fire, mark the conclusion partial instead of inventing CPA or ROAS.

The Google Ads Search terms report shows searches that triggered ads and can help identify phrases to add or exclude. Review a mature period and group terms into keep and expand, refine, exclude, or investigate. Keep campaign, query, region, device, language, cost, ad, landing page, and outcome together. Do not create one negative-keyword list from a term that is irrelevant for one service area but legitimate for a tourism or national product campaign. A high click-through rate does not prove a profitable order or qualified lead; connect the search to the page and business result.

Check budgets, landing pages, and New Zealand price context

Record the approved plan before deciding whether a campaign is overspending. Define the period, account time zone, NZD currency, campaign objective, shared budgets, seasonality, promotions, stock, freight, sales capacity, and outcome definition. Check whether national, regional, local, brand, and non-brand campaigns compete, whether a shared budget joins incompatible goals, and whether bidding optimises toward a clean primary conversion.

Inland Revenue’s GST guide is a useful reference when an ad, product page, checkout, invoice, and performance report describe value differently. Document whether revenue is GST-inclusive or exclusive, how freight and discounts are handled, and how refunds are treated. Do not use a single GST or freight assumption to make unlike orders comparable.

Open the final URL for each materially different campaign, region, product, service, or audience. Test the offer, price, delivery, postcode handling, form or phone route, opening hours, stock, consent flow, mobile experience, and intended conversion. Flag an ad promising nationwide delivery when the page excludes rural areas, a regional campaign landing on a generic page, a stale promotion, a lead form accepting an unserviceable address, or a call event that counts an unanswered call. A relevant ad cannot repair a page that cannot fulfil the promise.

Prioritise findings by risk and evidence

Rank findings by financial exposure, customer impact, confidence, reversibility, and owner. Preserve the exact account, campaign, period, region, query, URL, event, and source behind each item.

Use “unknown” when evidence is unavailable. Do not call a missing source a zero simply to complete a scorecard. The audit is stronger when it distinguishes a failure from a question that still needs an owner.

A repeatable free Google Ads audit workflow for New Zealand

1. Set the contract. Record the account, campaigns, regions, dates, NZD definition, business objective, reviewer, and decisions outside the audit’s authority.
2. Inspect structure. Map accounts, campaign types, networks, locations, budgets, bidding, audiences, ads, products, landing pages, and service boundaries.
3. Validate measurement. Trace primary conversions to an order, qualified lead, booked job, booking, subscription, or other business record. Check duplicates, imports, source freshness, and lag.
4. Review delivery. Compare settings with impressions, clicks, cost, search terms, devices, regions, postcodes, products, services, and intended customers.
5. Reconcile economics. Keep spend, revenue, GST, freight, margin, lead quality, sales stage, refunds, returns, capacity, and time-zone definitions separate until they agree.
6. Prioritise findings. Preserve evidence, confidence, impact, owner, approval requirement, expiry, and rollback or verification plan.
7. Review with the responsible team. The account, analytics, sales, operations, finance, and compliance owners may need different evidence.
8. Verify the next period. After an approved change, compare the intended scope with the next complete period. A saved setting or successful API response is not proof of a changed business result.

Common mistakes include treating New Zealand as one audience, assuming a region target equals a delivery zone, using clicks as the outcome, combining time zones or GST definitions, reacting to immature data, applying one negative list everywhere, calling a partial source zero, and turning every finding into an automatic edit. Clear scope and evidence are more useful than a perfect-looking score.

What the free adz.so audit can and cannot do

adz.so is an evidence-first account review. Its workflow can help organise supported Google Ads checks and show the reasoning behind a finding. It does not mean the product implements every regional, bidding, CRM, ecommerce, freight, GST, cultural, compliance, or operational decision discussed here. Confirm the live workflow and supported account scope before connecting an account.

For an agency or multi-account review, the free Google Ads audit for agencies is a suitable starting point. For a product-led account, the free Google Ads audit for ecommerce keeps the focus on products, orders, feeds, freight, and revenue evidence. Keep approvals, customer data, account changes, and final business decisions with the responsible team.

Practical next steps

Begin with one New Zealand customer account, one date range, one business objective, and one owner. State whether the market is nationwide, selected regions, cities, postcodes, radii, or a combination. Record location settings, conversion definitions, search-term evidence, budget plan, landing-page tests, GST or freight definitions, and business outcomes for that same scope.

The best result is not a “healthy” label. It is a defensible statement such as: “Regional campaigns reached approved service areas, but booked-job linkage is missing,” or “Shopping spend is concentrated in available products, while freight and returns are too immature to judge contribution.” Recheck Google’s location guidance, conversion documentation, and Search terms report guidance during the review, and keep source freshness and unresolved limitations in the audit record.
