Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-6a53f38faa80318d quantitative
Watercare, the water utility owned by Auckland Council, began replacing residential mechanical meters with smart meters in April 2022.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare's April 2022 release says residents would start to have their old mechanical meters replaced that week as the residential rollout began. The Commerce Commission's Crown monitor report records Auckland Council as Watercare's shareholder, a non-financial one since 1 July 2025.
Caveat
Schools and some large customers already had smart meters a few months before the residential start, so April 2022 dates the household rollout, not the first meter.

Sources carrying this claim

  1. Watercare — Smart water meter rollout begins (7 Apr 2022)
  2. Commerce Commission — Watercare's performance in 2025, Crown monitor report (28 Nov 2025)
Claim 2 clm-4c86acb37b14edfe descriptive
The meters take a reading every half hour and send the data once a day
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare states in 2022 that the meters take readings every half an hour and the data is sent daily; its current meter page repeats that readings are taken every thirty minutes and sent once daily.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Watercare — Smart water meter rollout begins (7 Apr 2022)
  2. Watercare — Smart meters (customer information page)
Claim 3 clm-ddce5f585c157512 descriptive
its meter page promises monthly bills on actual use, usage data in its app and notifications of possible leaks
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare's smart meter page lists three benefits: monthly bills based on actual water use, live visibility of monthly, daily and half-hourly use in its app, and quick notification of possible leaks through the app.
Caveat
These are the utility's stated benefits; no source reports how many customers receive leak notifications or monthly actual-use bills.

  1. Watercare — Smart meters (customer information page)
Claim 4 clm-cddf34ed43846362 quantitative
In April 2021 a council committee adopted a pathway to smart meters on all homes by about 2034
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
RNZ reports that Auckland Council's Environment and Climate Change committee opted for a water-strategy pathway whose components included all residential properties having smart water meters by about 2034, alongside nearly 80,000 smart meters in the following four years.
Caveat
A target in a strategy, not a commitment by Watercare's board; Watercare said in 2022 it would replace all meters 'over the next decade'.

Sources carrying this claim

  1. RNZ — Auckland smart water meter rollout aims for 80,000 in four years (15 Apr 2021)
Claim 5 clm-fd09fc494f1773c4 quantitative
in June 2026 the supplier Itron announced 100,000 meters towards almost half a million
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Itron's release says Watercare is upgrading existing mechanical meters with 100,000 Itron Intelis wSource digital meters as part of its plan to connect almost half a million smart meters across the Auckland region.
Caveat
Vendor press release; Watercare's own statement of the contract and its timetable was not located.

Sources carrying this claim

  1. Itron — Itron Collaborates with Watercare Services for New Zealand's Largest Smart Water Meter Upgrade (15 Jun 2026)
Claim 6 clm-2e19db10ddc3c33f quantitative
in June 2025 Watercare told RNZ that around 70,000 of its roughly 500,000 meters were smart
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
RNZ's Checkpoint report states that Watercare has around 500,000 meters and that around 70,000 of them are smart meters.
Caveat
The same report also speaks of 40,000 meters installed since 2022, and a later report gives 40,000 as the count of one model alone; the totals are not reconciled in any source.

  1. RNZ — Problems with Auckland's Watercare bills after more than 13,000 smart meters not working (25 Jun 2025)
Claim 7 clm-4abeaf98951cfebe descriptive
two meter models have each produced billing faults
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Newsroom reported in 2023 that Landis+Gyr meters were over-counting on customers' bills; RNZ reported in 2025 that a third of Watercare's 40,000 EDMI meters were faulty, EDMI being one of two smart meter models rolled out since 2022.

Claim 8 clm-1976990ef419a949 quantitative
in April 2022 it said meter data had flagged a school losing more than 66,000 litres a day
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare's 2022 release says smart meter data allowed it to alert an Auckland primary school to a possible leak, found under volcanic rock and losing more than 66,000 litres a day.
Caveat
A single example reported by the utility, not a measured programme result.

Sources carrying this claim

  1. Watercare — Smart water meter rollout begins (7 Apr 2022)
Claim 9 clm-901e5b88f5ce1740 quantitative
in March 2023 it described a school leak under volcanic rock as losing about 46 litres every minute
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare's 2023 release on commercial meter loggers describes a school whose use rose from about 6,000 to more than 70,000 litres a day, where a leak under volcanic rock was losing about 46 litres every minute.
Caveat
Neither release says whether the two descriptions refer to the same school; both are the utility's own examples.

Claim 10 clm-f7446041f32fccbf quantitative

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Newsroom reports that 17,000 Landis+Gyr smart meters wrongly added about six litres a day to each customer's bill, that the defect went unnoticed for nearly a year, that households overpaid $9.85 on average, and that Landis+Gyr would refund customers through Watercare credits.

In 2025 a fault in EDMI meters stopped them sending data while they kept recording, producing zero-use bills followed by catch-up bills
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Watercare's head of retail operations told RNZ the fault means the meter eventually stops sending data but keeps recording water use; affected customers received bills showing zero use, and returning meters to manual reading led to catch-up bills higher than previous months.

No claim-specific caveat recorded

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Crown monitor report states that Watercare's leakage in FY25 was 119.2 litres per connection per day and that it met the Charter target of no more than 140; it also notes Watercare did not meet the separate 98.2-litre economic-level-of-leakage target, which it treats as a management tool.

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The report says Watercare minimises water loss through its asset plan, by responding to leak notifications, with acoustic leak detection and by using water meter data to monitor and manage losses; it does not discuss the smart meter programme.

Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
RNZ reports Watercare said it had known about problems with one meter type since October 2024; customers described zero-use bills from May 2025, and one said Watercare made no effort to contact him and he raised the issue himself. Watercare then said it would start contacting customers proactively.
Caveat
Customer accounts as reported by RNZ; the number of customers who raised the fault themselves is not stated.

What the mapping says
Utilities Disputes Commissioner Neil Mallon told RNZ he would expect a company with meter issues to be really proactive with communication, that water companies are voluntary participants in the scheme, and that he would like to see them become mandatory, like energy companies.
Caveat
Whether Watercare is a member of the voluntary scheme is not stated in the report.
