As far as possible we have included the following accessibility features in this website:

  • The website is designed and built to be accessible
  • The site includes a stylesheet that optimises printing
  • You can navigate around the site using the tab key
  • You can change the size of the text
  • Links tell you where they are taking you and why
  • Images, graphs and charts are described in plain English
  • Audio and visual material on this site is accessible

In some parts of the website - where older legacy content has been imported from the previous MacDiarmid Institute website - accessibility may not be at such a high level. We're working on these pages to bring them up to scratch.

Accessible design

The website is designed and built to be accessible. It uses cascading style sheets for visual layout. If your browsing device does not support style sheets, the content of each page is still readable.

The site has been designed so that text and background colours are at an accessible contrast ratio and meet the Government web standards requirements.

Print stylesheet

This site uses a print stylesheet which allows a page to be printed straight from the browser in a 'print-friendly' manner and eliminates unnecessary graphical elements.

This means that only the main content from the page will be printed — the top banner and navigation links and images will not be printed.

Tab key

You can use the tab key to navigate around the site, and we have provided skip links for screen readers so you can jump to elements that repeat on every page.

Changing the size of the text

You can change the text size on any web page on this site. Most browsers (with the exception of Internet Explorer) allow resizing of text via the following keyboard commands:

Windows: CTRL key and the '+' or '-' keys.
Mac: Command or Apple key and the '+' or '-' keys.

To change the font size in Internet Explorer, go to the View Menu and select Text Size.


As much as possible, links around this site have been written to explain where they take you. Navigation elements are all in plain text, not images.

We have linked to other sites where we think the information they contain may be of value to you. We can't guarantee that other sites will be accessible.

If you think a link is broken, send us an email or call us on +64 4 463 6927 to let us know.

Images, graphs, and charts

All new content images such as photos, charts and graphs have meaningful plain English descriptions that can be read by screen readers. In legacy content imported from the old MacDiarmid Institute website, this may not always be the case. We're working to improve this content.

Accessible audio and visual material

We are working towards ensuring that audio and visual material on this site is accessible. We are aiming for:

  • Audio-only recordings are accompanied by a text transcript that includes descriptions of all visual and auditory information.
  • Video-only recordings have a descriptive text transcript (that includes all information conveyed visually) or an audio description (voice-over track).
  • Video and audio recordings have captions for all dialogue and meaningful audio content, accompanied by a descriptive text transcript on the page.

At the moment, some of our videos are captioned, others are not. We currently don't have transcripts for our audio or video recordings, but we plan to have this in the future.
