Tatuanui is a settlement and rural community in the Matamata-Piako District and Waikato region of New Zealand's North Island.

The name was shortened to Tatua but was renamed to Tatuanui to avoid confusion with another place.

Tatua is an independent co-operative dairy company owned by 101 shareholder farms, all located within a 12 kilometre radius of the processing site.

[8] The co-operative has maintained a strong independent history within the New Zealand dairy industry.

In the 2001 mega-merger for the New Zealand dairy industry which formed Fonterra, Tatua shareholders decided to remain independent.

[9] Tatua often records the highest payout for milk solids to the farmer shareholders in New Zealand.

[10] While the high level of payout is partly due to a small catchment area (which reduces processing costs), the high financial performance of Tatua has been attributed to its focus on value-added dairy products rather than traditional, mass-produced, commodity-based milk products such as milk powder, butter and cheese.

[11] A giant model of a can of whipped cream sits outside the factory as an landmark for the township.

[15] The Ministry for Primary Industries held a public meeting in the township in October 2019 following several new Waikato cases of the cattle disease Mycoplasma bovis.

[23] The school buildings, drains and playground were built by volunteers from the local community, and caretaking activities have traditionally been done at parent working bees and by students during class time.
