About

The New Zealand Health Survey was first undertaken in 1992/93, with further surveys taking place in 1996/97, 2002/03 and 2006/07. The Ministry of Health's wider health survey programme included surveys on nutrition; tobacco, alcohol and drug use; mental health; and oral health. From 2011, the Ministry of Health integrated the New Zealand Health Survey and these other surveys from its wider survey programme into a single survey, which is now in continuous operation.

The New Zealand Health Survey conducts face-to-face interviews with over 13,000 adults and the parents or primary caregivers of over 4000 children annually. The survey collects a wealth of information on the health and wellbeing of New Zealanders. Every year, it includes a core set of questions, which help the Ministry of Health identify key issues and monitor trends.

The Regional Data Explorer presents the most recent results, as well as trends, for each District Health Board, Public Health Unit and Regional Council. It provides information on health behaviours and risk factors, health status, long-term conditions, and access to and use of health care for both adults and children.

The Regional Data Explorer presents data that you can use to answer the following questions.

1. How do the results for one indicator vary across regions?
2. How do a region's results differ from the national results?
3. How do the indicators vary by sex, age, ethnicity or neighbourhood deprivation within a particular region? Do sub-population group differences in an indicator still show after adjusting for differences in the demographic structure of the populations being compared?
4. How do the results vary over time for a region?

Acknowledgements

This Regional Data Explorer was co-developed by EPI-interactive and the Health and Disability Intelligence Unit at the Ministry of Health.

The New Zealand Health Survey would not have been possible without the support and enthusiasm of many individuals, including the many thousands of New Zealanders who gave their time to participate in it and the interviewers who worked so diligently to collect the data.

How to access survey microdata

Researchers can apply to access the Confidentialised Unit Record Files (CURFs) from Ministry of Health's population surveys after the key survey results have been released. CURFs have had all identifying information about individuals removed, and have been modified to protect individual information. You can view a list of available CURFs at Access to survey microdata.

Please note: This app may time-out if left inactive for a while or when the internet connection is interrupted, which will cause the screen to grey-out. To use the app again, refresh the page.

Using links: Text in light blue in the app indicates a clickable link either to another page or to download a document. Make sure pop-up blockers in your browser are disabled to use this feature.

Comparing regional data: Be careful when comparing District Health Boards (DHBs), Public Health Units (PHUs) or Regional Councils (REGCs)! Each region has a different sociodemographic profile which affects regional indicator patterns (see http://www.health.govt.nz/new-zealand-health-system/my-dhb for more information on the differences between each DHBs' population). Also, some regions are smaller than others which means that the figures we provide tend to be more accurate for larger regions than for smaller regions.

Neighbourhood deprivation: In the Regional Data Explorer, neighbourhood deprivation (NZDep2013) rankings have been split into quintiles. The lowest quintile indicates the lowest levels of deprivation (rich); the highest quintile indicates that the neighbourhood experiences the highest levels of deprivation (poor). Not everyone who lives in a deprived neighbourhood will be deprived themselves.

How do I navigate the Regional Data Explorer?

• On the Home page you can directly access the three main sections of the Explorer. Click the My topic, My region or Subgroup results boxes to go to the respective page. Also, direct links to Methodology (1) and Download datasets (2) are provided on the Home page.

  

• On each page, use the tab panel (1) to navigate to another page. Use the Home button (2) or click the Ministry of Health logo (3) to return to the Home screen. Clicking the Ministry of Health logo on the Home page will take you to the New Zealand Health Survey landing page.

  

What filters and outputs are available?

• Filters are available in the left panel. Depending on the page you are on (My topic, My region or Subgroup results) filters might vary slightly (1):

  • Region type: select either District Health Boards, Public Health Units or Regional Councils
  • Population and indicator (or topic): select the topic and indicators you are interested in
  • Time period: either pooled year or single year data is available
    Tip: Choose pooled years for more accurate results as more data is available, particularly for smaller regions.

• Click the headings in the left panel to expand advanced filters (2):

  • Sociodemographics: choose Sex and either Age groups, Ethnic groups or Neighbourhood deprivation
  • Choose between unadjusted or age-standardised data

• Choose different outputs for your selected filters, for example, Chart, Time series, Map or Table (3). Further filter or sort options may be available for each output (4).

  
• Note: Your filter selection in the left panel is specific to each page. This means when you, for example, navigate from the My topic to the My region page your selection in the left panel doesn't get carried over. When you return to My topic the left panel selection you've chosen at the time is available again.

How do I get an overview of all topics and indicators?

• Click the Show indicator overview button (1) on the My topic or Subgroup results page for an overview of all available topics and indicators.

  

• Scroll down using the browser scroll bar to access all topics and indicators (1). You can click an indicator link to directly select an indicator (2). Alternatively click the Close button (3) or click anywhere on the grey background to return to the page where you came from.

  

How can I access exact values for the data points in the charts and maps?

• All charts provide additional information (eg prevalence value with confidence interval) when hovering with your mouse over the bars of a bar chart (1) or data points in a line chart (2).

  
  
  

• Additional information is also available when hovering over a region in the map on the My topic page, for example, next to the prevalence or mean value for the selected region also the confidence interval (CI) and comparison values for New Zealand are displayed.

  

What is the best way to print charts and maps?

• Charts and map outputs of the Explorer have an option available to download the output in HTML format. Click the corresponding link under Download to save the output as a single HTML file to your computer.

  

• Once downloaded open the local HTML file in your browser - this will just show the chart or map in a browser tab. Now you can use your browser print function to print or PDF export the chart or map:

  • Windows PC: press [Ctrl] - P on your keyboard
  • Mac: press Command - P on your keyboard

• Tips for easy printing:

  • Resize the browser window after opening the local HTML file to resize or change the proportions of the chart.
  • On the map HTML output hover over the map and use the scroll wheel of your mouse to zoom in or out. Then print with the desired zoom level.
  • Use a snipping tool to export just a selected area. On Windows PCs search for 'Snipping Tool', on Mac press Command - Shift - 4.
  • Printing an entire page of the Explorer with your browser without using the HTML export is not recommended as it will mix up the different elements on the page. Either use the HTML export or screenshot the page.

What data downloads are available?

• Downloads of the data displayed are available via the links under Download on the My topic, My region and Subgroup results pages. Click the Download links to download data in either CSV or HTML format.

  

• Go to the Download datasets page to download data for all indicators. The following downloads are available for the different region types:

  • District Health Board prevalence and mean data
  • District Health Board adjusted ratios (subgroup comparison)
  • Public Health Unit prevalence and mean data
  • Public Health Unit adjusted ratios (subgroup comparison)
  • Regional Council prevalence and mean data
  • Regional Council adjusted ratios (subgroup comparison)

• Note: When opening the CSV files with Excel some values in the 'agegroup' column are converted into the wrong cell format and show as dates. To manually assign the correct format you can follow the steps below:

  • Save a copy of the file
  • Rename it by adding .txt to the end of the file name
  • Open Excel and click 'Data' > From Text
  • Go through the import wizard and select comma delimited file. In Step 3 you can choose a format for each column. Select the age-group column and select 'text' format. Click Finish.

Where do I get more information about the data displayed?

• Some of the chart and table headings have Info buttons added. Click an Info button to get further explanation; for example, of how significance is measured or what the symbols used in the tables mean.

  
• Some of the tables contain footnotes with further explanation. You may need to scroll down the page to see the footnote.
• Go to the Methodology page for an overview of the sample design and analysis. You also find corrections to previously published data and references to other related publications on this page..
