But comments started on the council's Facebook page on Saturday, from residents at Ruakaka, Tutukaka, One Tree Pt and Whangarei Heads saying the extra collection on the 29th and 30th did not happen.
As a result, rubbish sat piled up for several days waiting to be picked up.
An apology, revealing the collections were only planned to start this week, was first posted in the comments section of two posts on the council's Facebook page on Wednesday.
"We would like to apologise for the error in the starting date for extra coastal rubbish collections. The extra collections start week beginning 1 January [this week], not 26 December."
"Our contractor is currently working hard to clear any build-up of rubbish and recycling. Please try to stick to the one recycling bin if you can, otherwise it's going to take a lot longer to clear any backlog."
Earlier in the holiday break Christmas Day caused some confusion for urban collection, with many rubbish bags and recycling bins put out on kerbsides on their usual day, rather than a day later as scheduled.
Contractors had Christmas Day off, so each of the collection days were put back a day, and those usually collected on Friday were collected on Saturday, December 30.
Council spokeswoman Ann Midson said rubbish had not been collected on Christmas Day.
