Land Transport Act 1998, ss 8, 37–39

You must not drive carelessly or without reasonable consideration for other people. For this you can be fined up to $3,000 and disqualified for a period decided by the judge.

If you injure or kill someone through careless or inconsiderate driving, you can be imprisoned for up to three months or fined up to $4,500, and you must be disqualified for at least six months.

When someone is injured or killed because of your careless driving, the penalty is greater still if you were speeding, or overtaking illegally, or on the wrong side of the road. In those cases you can be imprisoned for up to three years or fined up to $10,000, and you must be disqualified for at least one year.

Note: Careless driving can be committed with any vehicle, not just a motor vehicle. This can include bicycles, skateboards, in-line skates, and roller skates.

Land Transport (Road User) Rule 2004, rule 7.3A

In general, you cannot use your mobile phone while driving. This ban covers situations where you’re holding the phone and using it to text, email, make calls, watch videos, or for any other communication. It includes when you’re stopping at an intersection, traffic lights, or you’re waiting in a queue of traffic. The penalty for this is a $150 fine and 20 demerit points.

The only time you can use your mobile phone while driving is when it’s “hands-free” – for example, when your phone is mounted on the dashboard with voice recognition on. NZTA recommends this for things like navigation and music that you set up before you start driving.
