Waikato District Health Board
district health board of New Zealand
The Waikato District Health Board (Waikato DHB) was a district health board that provided healthcare to the Waikato region of New Zealand.
History
The Waikato District Health Board, like most other district health boards, came into effect on 1 January 2001 established by the New Zealand Public Health and Disability Act 2000.
2021 Ransomware attack
In mid-May 2021, the Waikato District Health Board's hospital computer systems and phone lines were affected by a ransomware attack. On 25 May, an unidentified group claimed responsibility for the hack and issued an ultimatum to the Waikato DHB, having obtained sensitive data about patients, staff and finances. Hackers later dumped confidential medical, financial and patients' data onto the dark web, forcing the DHB to work with cyber-experts to minimise any potential privacy disclosures.
The Waikato DHB and New Zealand Government ruled out paying the ransom. By mid-June 2021, the Waikato DHB had managed to restore most health services and operations but faced a backlog of outpatient appointments due to the disruption caused by the ransomware attack.
Dissolution
On 1 July 2022, the Waikato DHB and the 19 other district health boards were disestablished, with Te Whatu Ora (Health New Zealand) assuming their former functions and operations including hospitals and health services. The Waikato DHB was brought under Te Whatu Ora's Te Manawa Taki division.
Geographic area
The area covered by the Waikato District Health Board is defined in Schedule 1 of the New Zealand Public Health and Disability Act 2000 and based on territorial authority and ward boundaries as constituted as at 1 January 2001.

Why this record matters
“Waikato District Health Board” is worth following because a concise public description often conceals a longer documentary argument. Here, Waikato, District and Health provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q30281300. VIAF identifies the subject as 131684560. The Library of Congress control number is no2002011921. Authority coordinates are -37.803, 175.282. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2000, 2021 and 2022.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
