Drink-Driving Charges in Otago, NZ — Free Legal Information

Drink Driving in Otago — what to do right now

First, know which charge you're facing. Driving with more than 250 but not more than 400 micrograms of alcohol per litre of breath (or 50–80mg of alcohol per 100ml of blood) is an infringement — an on-the-spot fine and 50 demerit points, no criminal record and no court (Land Transport Act 1998, s56(1A) and s56(2A)). Over 400 micrograms of breath alcohol, or over 80mg of blood alcohol, is a criminal charge heard in the District Court (s56(1) and s56(2)), and on conviction the court must disqualify you from driving for at least six months. If you've been charged criminally, the date on your summons is the date you must appear at the Dunedin District Court. Get free advice from Community Law Otago or a lawyer before that date — don't just turn up and plead guilty without understanding your options.

The law in Otago: Drink Driving

New Zealand has one national legal system — there is no state or provincial drink-driving law, so the rules in Otago are exactly the same as in Auckland or Christchurch. What is local is the court: charges arising in the Otago region are dealt with at the Dunedin District Court (the District Court and High Court share the building on the corner of Stuart and Dunbar Streets), with sittings also held at Queenstown and Alexandra (judge-alone trials) and Oamaru (a hearings location, registry at Timaru). Serious cases or jury trials are heard in the High Court at Dunedin.

The offence is set by the Land Transport Act 1998, section 56. For an adult driver (20 and over), the criminal limits are more than 400 micrograms of alcohol per litre of breath (s56(1)) or more than 80 milligrams of alcohol per 100 millilitres of blood (s56(2)). Below that, between 250 and 400 micrograms of breath alcohol — or 50 to 80mg of blood alcohol — is an infringement offence (s56(1A), s56(2A)): an on-the-spot fine and demerit points rather than a charge in court. For drivers under 20 the limit is zero in practice: more than 150 micrograms of breath alcohol (or more than 30mg of blood) is a criminal offence under s57, and any alcohol at all below that is an infringement. Holders of an alcohol interlock licence or a zero-alcohol licence must also drive with no measurable alcohol (s57AA).

On a first or second criminal drink-driving conviction the maximum penalty is three months' imprisonment or a fine of up to $4,500, and the court must disqualify you from driving for six months or more (s56(3)). On a third or subsequent conviction the maximum is two years' imprisonment or a $6,000 fine, with disqualification of more than one year (s56(4)). Two further rules catch people out: if your reading is at or above 800 micrograms of breath alcohol (or 160mg of blood), or you have a drink-driving conviction in the past five years, the court must impose a mandatory alcohol interlock sentence (s65AB–s65AC) rather than a flat disqualification. And police can suspend your licence at the roadside for 28 days on the spot — if you blow over 400 micrograms with a relevant conviction in the last four years, or over 130mg of blood alcohol even as a first offender.

A drink-driving charge is criminal, not a personal-injury matter, so New Zealand's accident-compensation scheme (ACC) is not relevant to the charge itself — but be aware that if you cause injury or death while over the limit you face far more serious charges (s61, s62) and ACC bars most civil injury claims against you in any event.

The Two Deadlines People in Otago Miss

Two things blindside people charged with drink-driving in Otago. The first is the 28-day roadside suspension: police can take your licence on the spot — before any court date — if you blow over 400 micrograms with a relevant conviction in the last four years, or over 130mg of blood alcohol even on a first offence. That suspension runs immediately and separately from anything the court does. The second is the court date itself: the date printed on your summons is the day you must appear at the Dunedin District Court, and turning up unprepared, or pleading guilty without advice, can lock in a longer disqualification or an interlock sentence you might have avoided. Free help is available before that date — use it. This is general information, not legal advice about your case.

Likely outcomes & penalties

Every drink-driving charge turns on its own facts — your exact reading, whether it's a first offence or a repeat, your age, and whether anyone was hurt. These are the statutory ranges under the Land Transport Act 1998, not predictions about your case.

Infringement band (250–400 mcg breath / 50–80mg blood)

Not a criminal charge and no court appearance — an infringement fee and 50 demerit points apply instead (s56(1A), s56(2A)). Accumulating 100 or more demerit points within two years brings its own three-month licence suspension, so even an infringement matters.

First or second adult conviction (over 400 mcg / 80mg)

Maximum three months' imprisonment or a fine of up to $4,500, and the court must disqualify you for six months or more (s56(3)). Most first offenders are fined rather than jailed, but the mandatory disqualification still applies unless a special-reasons exception under s81 is made out.

Third or subsequent conviction

Maximum two years' imprisonment or a $6,000 fine, with mandatory disqualification of more than one year (s56(4)). Past convictions for related offences count toward the tally, and a mandatory alcohol interlock sentence is likely.

High reading or repeat offending

If your reading is at or over 800 micrograms of breath alcohol (160mg of blood), or you have a drink-drive conviction in the past five years, the court must impose a mandatory alcohol interlock sentence (s65AB–s65AC): a disqualification period followed by an interlock licence and at least 12 months on the device before you can apply to exit.

Mistakes to avoid

⚠️

Assuming Otago has its own drink-driving rules — it doesn't. The Land Transport Act 1998 applies identically across New Zealand; only the court that hears your charge (the Dunedin District Court) is local.

⚠️

Pleading guilty at the first appearance without advice, thinking it will look better — the disqualification is mandatory either way, and a rushed plea can cost you arguments about your reading, the procedure, or an interlock alternative.

⚠️

Treating the 28-day roadside suspension as the whole punishment — it runs separately from, and in addition to, whatever the court later orders on the charge itself.

⚠️

Ignoring an infringement notice because 'it's not criminal' — the demerit points still mount, and 100 points in two years triggers a separate three-month suspension.

⚠️

Driving while disqualified to get to work — that is a further criminal offence with heavier penalties; a limited or alcohol interlock licence applied for properly is the lawful route to keep driving.

How it works

Find your charge and your date. Check whether you've been charged criminally (a summons with a Dunedin District Court date) or given an infringement notice, and note any 28-day roadside suspension already imposed. The two run separately.

Get free, plain-English information before you respond. Community Law Otago and the Citizens Advice Bureau give free guidance, and the New Zealand Law Society can refer you to a lawyer. Understand your reading, your options and the likely disqualification before any plea.

Decide on representation and, if needed, a limited or interlock licence. For a serious or repeat charge, a lawyer can advise on plea, on a possible special-reasons argument under s81, and on applying for an alcohol interlock or limited licence so you can keep driving lawfully.

FAQ — Drink Driving in Otago

What is the legal drink-driving limit in Otago, New Zealand?

The limit is national, not regional. For adults (20 and over) it is 250 micrograms of alcohol per litre of breath or 50 milligrams per 100ml of blood. Between those limits and 400 micrograms / 80mg it's an infringement; above 400 micrograms or 80mg it's a criminal charge heard at the Dunedin District Court (Land Transport Act 1998, s56). For drivers under 20 the limit is effectively zero.

Which court will my drink-driving charge be heard in if I'm in Otago?

Almost always the Dunedin District Court, on the corner of Stuart and Dunbar Streets (entrance on Dunbar Street). Some matters are dealt with at Queenstown, Alexandra or Oamaru sittings, and serious cases or jury trials go to the High Court at Dunedin. The date on your summons is the day you must appear.

What's the difference between an infringement and a criminal drink-driving charge?

An infringement (250–400 micrograms of breath alcohol, or 50–80mg of blood) means an on-the-spot fine and demerit points — no court and no criminal record (s56(1A), s56(2A)). Over 400 micrograms or 80mg is a criminal charge: you must go to the District Court, and on conviction the court must disqualify you from driving.

What is the penalty for a first drink-driving offence in New Zealand?

For a first or second adult conviction the maximum is three months' imprisonment or a fine of up to $4,500, and the court must disqualify you from driving for six months or more (s56(3)). Most first offenders are fined rather than jailed, but the disqualification is mandatory unless a special-reasons exception applies. Your exact reading and circumstances matter.

Will I lose my licence on the spot in Otago?

You can. Police can impose an immediate 28-day roadside suspension if you blow over 400 micrograms with a relevant drink-driving conviction in the last four years, or over 130mg of blood alcohol even as a first offender. This runs separately from, and in addition to, anything the court later decides.

What is an alcohol interlock sentence and when does it apply?

An alcohol interlock is a breath-testing device fitted to your car that won't let it start if it detects alcohol. The court must impose an interlock sentence if your reading is at or over 800 micrograms of breath alcohol (160mg of blood) or you have a drink-drive conviction in the past five years (s65AB–s65AC). You then serve a disqualification, get an interlock licence, and must run the device for at least 12 months.

I'm under 20 — are the rules different?

Yes. Drivers under 20 face a zero-alcohol limit. More than 150 micrograms of breath alcohol (or 30mg of blood) is a criminal offence with up to three months' imprisonment or a $2,250 fine and disqualification of three months or more (s57). Any alcohol below that level is an infringement with a fine and demerit points.

Can I get free legal help with a drink-driving charge in Otago?

Yes. Community Law Otago gives free advice by appointment in Dunedin and at outreach clinics around the region, the Citizens Advice Bureau gives free information, and you may qualify for government legal aid for a serious charge. The New Zealand Law Society can also refer you to a local lawyer.

Should I plead guilty at my first court date?

Not without advice. The disqualification is mandatory on conviction, so a quick guilty plea rarely helps and can cost you arguments about your reading, the police procedure, an interlock alternative, or a special-reasons application under s81. Get free guidance from Community Law Otago or a lawyer before you respond.

Does a drink-driving conviction from years ago still count against me?

It can. A third or subsequent conviction carries a heavier maximum — up to two years' imprisonment or a $6,000 fine and disqualification over a year (s56(4)) — and a drink-drive conviction within the past five years triggers a mandatory alcohol interlock sentence. The dates of your prior convictions matter, so it's worth checking your record.
