Occasionally I take a bit of a wander through http://maoridictionary.co.nz to see what I can learn and what combinations of interesting words will work. Exploring somewhat randomly is usually more meaningful for me, and likely to "stick".

After wandering through some new words I might check with a colleague who has more Te Reo Maori experience to check whether these words can be legitimately used in such a way.

Something I appreciate about http://maoridictionary.co.nz is the use of words in phrases and idioms. This is a helpful hint to proper usuage and a delightful glimpse into Maori culture.
