The 'Ekco' brand was introduced in NZ in around 1955 and lasted until around 1967.

'Ekco' branded equipment was manufactured by Radio (1936) Ltd, they had various distributors. Currently there are 12 documented models.

While the NZ use of the name Ekco was introduced in the 50's, the brand had been in New Zealand on and off since 1934.  The earliest note of Ekco radios being sold in New Zealand was in Christchurch at Butlers (N.Z.) Ltd back in 1934 and 35.  Then in 1936 it seems like everyone was selling the SW86, which was distributed in New Zealand by Speddings in Auckland.
