April 25, 2017: The same defect is found on Air New Zealand Career Board. With a quick study, the resources point to a company named “Snaphire” (resource name is com.snaphire.wicket.*). It seems the typo is with common template by Snaphire for both the two NZ government web sites.
This post is about human interface defect instead of codes or automation as usual. Couple of real world defects are discovered on web services with local business. It might be an indicator of demand on QA engineering, both automation and manual test. At least of a pattern is discovered, for example typo, it is easy to code the pattern of spelling check and word similarity calculation with basic NLP in Python or Java.
