Mondelez' external affairs manager Jake Hatton said "the vast majority of the revenue change is due to the factory closure, not sales revenue".
With the factory closure, the factory revenue is no longer counted in the New Zealand annual accounts, he said.
"There were a range of factors that impacted revenue last year including a number of one-time adjustments which included the factory closure, changes to customer inventory management, and the closure of the popular Cadbury World attraction, which was unfortunately out of our control," he said.
The New Zealand business continued to "perform strongly" and Mondelez was committed to investing in the New Zealand business and working closely" with thousands of local retail partners" to support growth.
The report noted that property, plant and equipment sold to other Mondelez subsidiaries during the year for a total $7.35 million, against no plant sales the previous year.
The "restructuring provision" for 2018 was $12.58 million, while in 2017 the post-employment benefits, including severance payments, was $18.34 million.
It appears post-employment benefits, including severance payments, totalled $19.51, with $1.18 million booked in 2017.
Employee remuneration in New Zealand fell from $35.8 million in 2017 to $13.6 million in
2018.
