Also licensed, in Hamilton: 46 we could not score
These hold a current licence on the same public register, checked the same way. We could not score them because they have too few public reviews to rank fairly, many are sole traders without a Google listing. They are shown alphabetically, not ranked, and their absence from the table above says nothing about their work.

Questions about this page
- Which plumber in Hamilton does KiwiChecked rank highest?
- iPlumber has the highest LocalScore (88.1) of the 12 we scored, assessed August 2026. LocalScore combines public reviews, licence records and time in business. Nobody pays to be scored.
- How many plumbers in Hamilton hold a current licence?
- 58 businesses in Hamilton appear on the public register for this trade. We could score 12 of them; the rest have too few public reviews to rank fairly and are listed unranked.
- Can a business pay to rank higher on KiwiChecked?
- No. Sponsorship is labelled and sits outside the ranking, and payment has no effect on any score. Claiming a listing does not change a score either.
How we scored these plumbers
LocalScore combines review quality and volume, how recent those reviews are, verified licence records, and how long the business has been registered. Licences are checked directly against the relevant public register rather than taken from the business. Full weightings are on our methodology page.
