Ko tēnei Te Wiki o Te Reo Māori. This is Māori Language Week.
The theme for this year is ‘Whāngaihia te reo ki ngā Mātua’ - 'Nurture the language in parents.' It is also the 40th anniversary of Māori Language Week and the Māori Language Commission has created some posters and resources to commemorate it.
Check them, out here: http://www.tetaurawhiri.govt.nz/a-matou-mahi/te-wiki-o-te-reo-maori-mi-nz/te-wiki-o-te-reo-maori-resources-mi-nz/
So whāngaihia te reo (nurture the language) and karawhiua (give it a go).
