TradeMe took a big drop in the rankings, falling nine places to equal 14th in the space of 12 months, prompting Ireland to ponder "is it still the brand of the people?"
Whittaker's took a gamble on rehiring Nigella Lawson for a new series of big-money television ads, after the British celebrity cook admitted last year she had used cocaine.
"The Nigella campaign broke new ground, ensuring high salience," Ireland added.
Nicola Leenman, brand manager of biscuits and candy at Pascall, was delighted their flagship Pineapple Lumps leapt five places into second spot.
"Pineapple Lumps are such an iconic New Zealand brand," she said. "We have been celebrating them as the hero of our Pascall range over the last year, telling iconic Kiwi stories and creating mouth watering Pineapple Lump recipes and this has obviously been reflected in the results.
"We are really happy that Pineapple Lumps are a New Zealand national treasure".
