Charged With Drink-Driving in Tasman? Here's What Happens Next at the Nelson District Court.

An excess breath or blood alcohol charge in the Tasman region is dealt with under one nationwide law — the Land Transport Act 1998 — but it plays out locally, with your case listed at the Nelson District Court on Bridge Street that serves Nelson, Richmond and the wider Tasman district. If your reading was over the criminal threshold, the consequences can include disqualification, a fine, and for higher readings a mandatory alcohol interlock. You don't have to face this confused or alone. This page explains the New Zealand law in plain English and points you to free local help in Nelson and Tasman. This is general legal information, not legal advice, and reading it does not create a lawyer-client relationship.

Drink Driving in Tasman — what to do right now

Do this first: find your charging paperwork and note your court date and your reading. In New Zealand an adult is over the criminal limit at more than 400 micrograms of alcohol per litre of breath, or more than 80 milligrams per 100 millilitres of blood (Land Transport Act 1998, s56). A reading in that range is prosecuted in the District Court — for Tasman that means the Nelson District Court — and a conviction carries automatic disqualification of at least six months. If your reading was at or over 400mcg you were likely also given an immediate 28-day roadside licence suspension by police. Don't ignore your court date, and get advice before you plead. Free help is available from Nelson Bays Community Law and the local duty lawyer at court.


The law in Tasman: Drink Driving

New Zealand has one national legal system — there are no state, provincial or regional drink-driving laws. The same Act applies in Tasman as in Auckland or Invercargill. What changes from place to place is where your case is heard and which local services can help you. Drink-driving charges arising in the Tasman district (Richmond, Motueka, Tākaka, Wakefield, Murchison and surrounds) are listed at the Nelson District Court at 200 Bridge Street, Nelson, which serves the Nelson and Tasman areas; the most serious matters or jury trials can be heard in the High Court at Nelson.

The core offence is in section 56 of the Land Transport Act 1998 — "contravention of specified breath or blood-alcohol limit." For an adult driver (20 and over) there are two tiers. The lower, infringement tier covers a breath reading over 250 but not more than 400 micrograms per litre, or a blood reading over 50 but not more than 80 milligrams per 100 millilitres: that is dealt with by an on-the-spot infringement fine and 50 demerit points, with no court appearance and no criminal record. The criminal tier begins above those numbers — more than 400 micrograms of alcohol per litre of breath, or more than 80 milligrams per 100 millilitres of blood — and that is what is prosecuted in the District Court.

Drivers under 20 face a zero-alcohol limit, and commercial and certain other drivers also face stricter rules. Refusing or failing to give an evidential breath or blood test (sections 60 and 62) is itself an offence, treated as seriously as being well over the limit. Police can impose an immediate 28-day roadside licence suspension on the spot for an evidential breath reading at or over 400mcg (or 80mg blood), or for a refusal — this is separate from, and runs before, anything the court later decides.

Penalties escalate with prior history. For a first or second drink-driving conviction the maximum is up to three months' imprisonment or a fine of up to $4,500, plus disqualification of six months or more. For a third or subsequent conviction the maximum rises to up to two years' imprisonment or a fine of up to $6,000, with disqualification of more than one year. Since 1 July 2018 an alcohol interlock sentence is mandatory for anyone caught at or over 800 micrograms of breath (or 160mg of blood), or who has a drink-driving conviction within the previous five years — the court orders an interlock device that prevents the car starting if alcohol is detected, with a minimum 12 months on the programme before applying to exit. A subsidy scheme exists for lower-income drivers on an interlock sentence. None of this is automatic in your favour — how the case is run, and how you plead, can change the outcome, which is why early advice matters.

Key Law

  • Land Transport Act 1998, s56 — contravention of specified breath or blood-alcohol limit (the main offence)
  • s56 limits (adult 20+): over 400 micrograms per litre of breath, or over 80 milligrams per 100ml of blood (criminal); 251–400mcg / 51–80mg is the lower infringement tier
  • Zero-alcohol limit for drivers under 20 (Land Transport Act 1998)
  • ss60 & 62 — refusing or failing to give a breath or blood specimen (an offence in its own right)
  • Alcohol interlock sentence mandatory from 1 July 2018 for readings at/over 800mcg breath (160mg blood) or a repeat within 5 years

Courts & Agencies

  • Nelson District Court (200 Bridge St, Nelson) — hears Tasman drink-driving charges from arraignment to sentencing
  • High Court at Nelson — the most serious matters and any jury trials
  • New Zealand Police — administer evidential testing and the immediate 28-day roadside suspension
  • NZ Transport Agency Waka Kotahi (NZTA) — administers licences, disqualifications and the alcohol interlock / zero alcohol licence schemes
  • Duty lawyer at the Nelson District Court — free on-the-day help for people without a lawyer

The Things That Catch People Out

  • 🚨 28 days — the immediate roadside licence suspension police can impose on the spot for a reading at/over 400mcg or a refusal, before any court date
  • 6 months — the minimum disqualification on a first or second conviction over the limit
  • 5 years — a prior drink-driving conviction inside this window triggers a mandatory alcohol interlock sentence
  • Court date — listed on your charging paperwork at the Nelson District Court; appearing (or arranging representation) is required
  • Refusing the test is not a way out — under ss60/62 a refusal is treated as seriously as a high reading

The 28-Day Roadside Suspension That Happens Before You Ever See a Judge

Here's what surprises many Tasman drivers: your licence trouble can start at the roadside, not in the courtroom. If you returned an evidential breath reading at or over 400 micrograms per litre — or refused the test — police can impose an immediate 28-day suspension on the spot under the Land Transport Act 1998, well before your first appearance at the Nelson District Court. That suspension runs regardless of how your court case eventually turns out, and a conviction later adds its own disqualification of six months or more on top. People often assume nothing happens until court and keep driving — which can lead to a far more serious driving-while-disqualified charge. Don't guess. Free, plain-English guidance is available from Nelson Bays Community Law and the duty lawyer at court so you understand exactly where your licence stands right now.


Likely outcomes & penalties

Every drink-driving case turns on its own facts — your reading, whether it's a first offence or a repeat within five years, whether anyone was hurt, and how the stop and testing were carried out. These are the maximum statutory ranges under the Land Transport Act 1998, not predictions about your case.
Infringement tier (251–400mcg breath / 51–80mg blood, adult)
An on-the-spot infringement fine (commonly around $200) and 50 demerit points. No court appearance and no criminal conviction — but accumulating demerit points can still lead to a licence suspension.
First or second offence over the limit
Heard at the Nelson District Court. Maximum of up to 3 months' imprisonment or a fine of up to $4,500, plus mandatory disqualification of six months or more. Most first offences resolve without a custodial sentence, but disqualification is expected.
High reading or repeat (interlock-mandatory)
A reading at/over 800mcg breath (160mg blood), or any drink-driving conviction within the previous 5 years, triggers a mandatory alcohol interlock sentence — an interlock device fitted to your car for a minimum of 12 months before you can apply to exit, followed by a zero alcohol licence period.
Third or subsequent offence
Maximum of up to 2 years' imprisonment or a fine of up to $6,000, with disqualification of more than one year, and the interlock regime generally applies. Aggravating facts such as injury can lift matters into far more serious offending.

Mistakes to avoid

⚠️
Assuming nothing happens until your court date — police can impose an immediate 28-day roadside licence suspension on the spot for a reading at/over 400mcg or a refusal, and driving during it risks a separate, more serious charge.
⚠️
Refusing the evidential breath or blood test thinking it avoids a conviction — under sections 60 and 62 a refusal is an offence treated as seriously as a high reading.
⚠️
Pleading guilty at your first appearance at the Nelson District Court without advice — the duty lawyer is free and can explain your options before you commit to a plea you can't easily undo.
⚠️
Not checking whether a prior conviction falls inside the five-year window — a repeat within five years makes an alcohol interlock sentence mandatory, which changes everything about the outcome.
⚠️
Forgetting that the limit is zero if you're under 20 — there is no "small amount is fine" allowance for younger drivers under New Zealand law.

How it works

1
Get free, plain-English information. This page and the local services it links to (Nelson Bays Community Law, the Citizens Advice Bureau, and the duty lawyer at the Nelson District Court) can help you understand the charge, the 28-day roadside suspension, and your court date — without cost. This is general legal information, not legal advice.
2
Understand your specific position before you plead. Your reading, your history within the past five years, and the testing procedure all matter. Knowing whether the interlock regime applies, and whether there are issues with how the stop or test was conducted, shapes what you do next at the Nelson District Court.
3
Arrange representation if you need it. If your case is serious or you simply want a lawyer, you may qualify for criminal legal aid, or you can engage a Nelson or Tasman lawyer who handles drink-driving matters. Apply for legal aid as soon as you are charged — don't wait for your court date.

FAQ — Drink Driving in Tasman

I've just been charged with drink-driving in Tasman — what's the first thing I should do?

Find your charging paperwork, note your court date and your reading, and don't drive if police gave you a 28-day roadside suspension. Then get free advice before you plead — Nelson Bays Community Law (0800 246 146) and the duty lawyer at the Nelson District Court can both help at no cost. Acting early, before your first appearance, gives you the most options.

Which court will my Tasman drink-driving case be heard in?

Drink-driving charges from the Tasman district — Richmond, Motueka, Tākaka, Wakefield, Murchison and surrounds — are listed at the Nelson District Court at 200 Bridge Street, Nelson, which serves the Nelson and Tasman areas. The most serious matters or any jury trial can be heard in the High Court at Nelson.

What is the legal alcohol limit for driving in New Zealand?

For an adult driver (20 and over), the criminal limit is more than 400 micrograms of alcohol per litre of breath, or more than 80 milligrams per 100 millilitres of blood, under section 56 of the Land Transport Act 1998. A lower reading of 251–400mcg breath (or 51–80mg blood) is an infringement dealt with by a fine and demerit points. Drivers under 20 have a zero-alcohol limit.

What's this 28-day suspension the police mentioned?

If your evidential breath reading was at or over 400 micrograms per litre — or you refused the test — police can impose an immediate 28-day licence suspension on the spot, before you ever go to court. It runs regardless of your court outcome, and driving during it can mean a separate, more serious charge. Get advice from Nelson Bays Community Law if you're unsure where your licence stands.

What happens if I refuse the breath or blood test?

Refusing or failing to give an evidential breath or blood specimen is itself an offence under sections 60 and 62 of the Land Transport Act 1998, and it's treated as seriously as returning a high reading — including disqualification and the possibility of an interlock sentence. It is generally not a way to avoid consequences.

Will I lose my licence for a first drink-driving offence?

If you're convicted of being over the criminal limit, disqualification of at least six months is mandatory on a first conviction, on top of any fine. The exact period and any interlock requirement depend on your reading and history. The duty lawyer at the Nelson District Court can explain what's likely in your case — for free.

What is an alcohol interlock and when is it required?

An alcohol interlock is a device fitted to your car that stops it starting if it detects alcohol. Since 1 July 2018 an interlock sentence is mandatory if your reading was at or over 800 micrograms of breath (160mg blood), or you have a drink-driving conviction within the previous five years. You must spend at least 12 months on the programme before applying to exit, and a subsidy exists for lower-income drivers.

Does a drink-driving conviction from years ago still matter?

Yes. A prior drink-driving conviction within the past five years makes an alcohol interlock sentence mandatory and can lift your new charge into more serious territory, and a third or subsequent conviction carries up to two years' imprisonment or a $6,000 fine and disqualification of more than a year. The date of any prior conviction is worth checking carefully.

Can I get free or low-cost legal help in Nelson or Tasman?

Yes. Nelson Bays Community Law gives free advice (0800 246 146), the duty lawyer at the Nelson District Court helps people without a lawyer on the day, and you may qualify for criminal legal aid through the Ministry of Justice — apply as soon as you're charged. The Citizens Advice Bureau can also point you in the right direction.

I'm not a New Zealand citizen — can I still get legal aid?

Yes. You do not have to be a New Zealand citizen or a permanent resident to qualify for criminal legal aid; eligibility turns on your income, assets and the seriousness of the charge. Apply through the Ministry of Justice as soon as you are charged, and take your court summons with you.
