The possible merger of NZME and Fairfax's New Zealand subsidiaries will have huge implications for media - if it gets Commerce Commission approval - but should have little impact on businesses associated with affected print publications and radio stations.
"This is certainly a seismic shift - we're in a period of huge change," said Gavin Ellis, senior lecturer in film, TV and media studies at Auckland University.
"Mainstream media are having to make decisions to ensure their survival, to stay in business."
However, he said advertisers, contractors and suppliers often have cross-company relationships and it should be business as usual.
"The truck that transports NZME publications from the printers in Ellerslie is likely to be also bringing up Fairfax publications. The NZME printing press in Ellerslie also prints the Sunday Star Times - there is already commercial co-operation between the two companies."
