The Ministry is migrating nzmaths content to Tāhurangi.
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz).
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024.
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

An influence that leads to results which are systematically less than (or greater than) the true value. For example, a biased sample is one in which the method used to create the sample would produce samples that are systematically unrepresentative of the population.
Note that random sampling can also produce an unrepresentative sample. This is not an example of bias because the random sampling process does not systematically produce unrepresentative samples and, if the process were repeated many times, the samples would balance out on average.
