According to this article on the Stuff website:
“New Zealand Post has unveiled a new $15 million logo and rebrand to visually unite its Courier Post, Pace and Rural Post courier services.
“Chief executive Dave Walsh said the state-owned enterprise, which was facing declining revenues in the letter business but rapid growth in its courier services, wanted to ensure the three brands had the same livery.
“Currently, NZ Post’s Rural Post vans are painted red, and its Pace urgent service or Courier Post vans yellow and red, which was confusing for customers.
“Walsh said it was not unusual for the company to reinvest in its brands.”
Clearly, it was lucrative for the PR/Advertising Agency involved; but worth it for the Post Office? Hmm.
