"However, it is possible that some people may still experience ill effects even though the pollution levels remain relatively low," The Ministry said.
"People who are more at risk include pregnant women, babies and children, those who suffer from asthma or other respiratory conditions, older people or those with chronic illnesses."
In a statement, the police said they were aware the conditions might be concerning, but listed the proper reasons the number should be called:
• There is car accident where people might be hurt, or cars are blocking the road;
• Someone has been assaulted and the offender is still there;
• You are afraid for your safety and or for those around you;
• You need an emergency Police response.
Social media has been flooded with pictures of the smoky, orange-tinged skies with some people calling it "eerie and scary".
Others say their thoughts are with Australia.

2.50pm..... photo from my study room window. It’s eerie and scary....... the effects of the bush fires in Australia dulled the sky in Auckland, it looks orange and dull black. pic.twitter.com/CyGgAGNMXt
This is the sky in Auckland this afternoon as the haze from the fires reached NZ....very eerie and pretty scary. If it’s like this here, what must Australia be experiencing 😞 pic.twitter.com/xQckuAiC8T
