The data we collect provides information about the composition of the wider public sector, the change in staff numbers by department, and how much was spent on contractors and consultants.

The composition of the wider public sector

The public sector employed around 436,700 people in 2021, 18.9% of New Zealand’s total workforce (2,313,400), as measured by Stats NZ’s Business Demography data. The majority (88%) work in central government (384,400) and 12% in local government (52,200).

Note that the central government sector comprises all public sector employees, except those in local government. This includes the Public Service, health sector (including District Health Boards), the education sector (including primary and secondary schools), and Crown entities.

Over the last 5 years, the overall public sector workforce increased by 13.7% (with central government up 13.9% and local government up 12.4%). This compares with an 8.9% growth in the private sector over the same period.

The sector composition of workforce varies amongst the regions (see the interactive dashboard below).

Change in staff numbers by department

There were 61,097 full-time equivalent (FTE) staff at 30 June 2021. This is an increase of 6.9% (or 3,948 FTEs) from 57,149 FTEs in 2020. The annual increase in 2020 was 8.6% (or 4,521).

Of the 36 Public Service departments and departmental agencies, 31 of them increased their FTE staff by taking on more staff, or filling roles that were vacant in June 2020. Five agencies reported a decrease.

The biggest increases in FTEs occurred at:

  • The Ministry of Social Development (MSD) (up 1,199). Around 70% of this growth was to support MSD’s role in the Government’s COVID-19 response, and the resulting increased demand for its services, as well as to support Budget priorities.
  • The Ministry for Business, Innovation and Employment (up 519). It was required to grow in 2021 to establish and lead the Government’s multi-agency MIQ response, with other growth necessary to deliver an expanded work programme.
  • The Ministry of Health (up 445). Most workforce growth across the Ministry was to support its role in the Government’s COVID-19 response, including the establishment of the COVID-19 Response Directorate and the COVID-19 Vaccination and Immunisation Programme.
  • The Ministry of Education (up 414). A focus on delivery of front-line service to support the national curriculum refresh, and delivering on the investments in improving outcomes for priority learners, including Māori learners and those with learning support needs drove workforce growth in 2021.
  • Oranga Tamariki Ministry for Children (up 330). The increase follows Cabinet’s approval for significant funding to support the development of the Ministry’s new operating model to transform the care system and meet new legislative obligations.

In contrast, the largest decrease was at Inland Revenue (down 617), as it continues to right-size following implementation of its Business Transformation Programme. There has been a significant decline in the number of fixed-term staff at the Department.

Department of Corrections remains the largest Public Service department (with 9,915 FTEs), closely followed by MSD (9,172). These 2 organisations make up 31.2% of the Public Service workforce.

Contractor and consultant expenditure

In 2020/21, Public Service organisations spent a total of $939.1 million on contractors and consultants. This was a decrease of 3% on the 2019/20 spend of $967.9 million, with the decrease driven by a decrease in spending at Inland Revenue, as it continues to right-size following implementation of its Business Transformation Programme. Total expenditure comprises operational expenditure of $603.4 million (down 1% from $609.4 million in 2019/120) and capital expenditure of $335.6 million (down 6.4 % from $358.5 million in 2019/20).

Operating expenditure on contractors and consultants was 10.3% of total Public Service workforce spend ($5,874.34 million), a reduction from 11.3% in 2019/20, 12.8% in 2018/19 and 13.4% in 2017/18. This reduction was due to contractor and consultant operating expenditure increasing at a slower rate over the past year than total workforce spend. This measure represents the balance between using external resources and building capacity and capability in the Public Service.

Note that some 2019/20 figures have been revised since they were first published. The reported total expenditure has changed from $974.9 million to $967.9 million.

Public Service contractor and consultant data for the 2017/18 year was the first to be published using our new guidance on how to report contractor and consultant expenditure. Before the new guidance, there was inconsistency in how organisations reported this expenditure.

Contractors and Consultants Guidance (PDF, 642 KB)

The focus is on operating expenditure, as the large one-off investments that capital expenditure typically represents are likely to have a different mix of public servants and contractors/consultants and the resulting expenditure is likely to be volatile over time due to the fixed-term nature of these projects.

Contractor and consultant expenditure definitions

Operating expenditure (OPEX) — this is the money spent for contractors and consultants that are not for the purpose of acquiring or developing assets.

Capital expenditure (CAPEX) — this is the money spent to acquire resources to develop assets, tangible and intangible, through procurement of contractors and consultants.

Total workforce spend — this is the sum of salary expenditure for permanent and fixed-term employees, and operational expenditure on contractors and consultants.
