"I am disgusted and saddened that these kids have done this I honestly can't believe it," one said.
"This kind of behaviour needs to be stopped. It is already a highly stressful time for everyone without disgusting cruel behaviour like this," another wrote.
A third added: "I'm hoping this video reaches the parents of these children as I'm sure they won't be impressed with their kids terrorising people like this."
When does New Zealand's Covid-19 lockdown start?
The lockdown will start at 11.59pm on Wednesday. That's when the coronavirus alert level will rise to 4 because two cases of Covid-19 have been identified as community transmission.
What should I do before the lockdown?
Firstly, don't panic. You will still be able to go to the supermarket where there will always be food.
All of Government Controller John Ombler, who heads the lockdown taskforce, said the supply chain will stay operational.
But you should prepare and start making arrangements.
This includes making plans with your families and loved ones, getting contact details within your community and thinking about how you'll make it through the lockdown.
You should already know if you're able to work from home.
If you're in a different part of the country, you should make immediate arrangements to get home.
Yes. You can still go to the supermarket, go for a walk, exercise and take the children to the park or the dog for a walk.
But you won't be able to interact with people outside of your self-isolation group.
For example, you can take your children to the beach but they shouldn't play with other children.
The goal of the lockdown is to limit the spread of the virus and if you're looking for exceptions to the rule, you've missed the point of it and means other New Zealanders would die, said Ombler.
It could also mean New Zealand stays in lockdown for longer than four weeks, said Ardern.
"If you hang out with that friend at a park or see that family member for lunch, you risk spreading Covid-19 and extending everyone's time in level 4."
