How big are taniwhas?

Taniwhas, legendary creatures in Māori mythology, are often described as large, powerful beings resembling reptiles or dragons. Their size can vary significantly in tales, but they are typically depicted as being enormous, capable of inhabiting rivers, lakes, and coastal areas. Some stories suggest they can grow to immense proportions, often exceeding the size of a canoe or even larger, reflecting their status as guardians of the waters. Ultimately, their exact size is symbolic, representing their strength and mystery rather than a fixed measurement.
