Waste Management operations manager Paul Withers said 2022 seemed to have been a great breeding year with many chicks on site already, and more to come.
"The adults are still nesting in different places so there will be plenty more chicks to come."
Staff at the landfill were enjoying having the chicks around, although the cheeky birds had been known to sneak into the break room and make a mess occasionally.
Maintenance tasks such as mowing were a little more complicated with the presence of pukeko nests.
Some patches of grass were going unmown as they were home to a nest, which could hold as many as 13 eggs.
Mr Withers said patrons of the landfill had enjoyed seeing the chicks, taking plenty of photos and videos.
"The adults are very protective and won’t let people get too close. The chicks will head for cover if you get too close, otherwise they seem oblivious to people being around."
"[It is] a great traffic-calming measure. People slow down to watch them and will give way if they are on the road."
