The short answer
Hamilton's emergency vet is the Waikato After Hours Veterinary Hospital, 574 Anglesea Street, phone 07 839 5656. It opens 6pm to 8am Monday to Thursday, runs all weekend from Friday 9am to Monday 8am, and is open 24 hours on public holidays. We could not find a Hamilton hospital open around the clock every day, so from Monday to Thursday between 8am and 6pm, and on Friday before 9am, call your regular vet.
Call ahead if you can. The hospital does not publish a consultation fee; it gives an estimate range and asks for a deposit before treatment. Emergency care is expensive, so ask for an estimate.

About the Waikato After Hours Veterinary Hospital
- What it is. It describes itself as a companion animal after-hours emergency clinic, the Waikato's vet emergency hospital, and your stand-in clinic until your regular vet opens.
- No appointment needed. No referral or appointment is necessary and walk-ins are welcome, but it asks you to call and say you are on your way.
- One vet on site. It says it has one veterinarian on site at a time and does not do home visits or call-outs.
- What it can do. It lists emergency treatment and critical care, digital x-ray, surgery, blood analysis, treatment of poisoning, blood transfusions and CT scanning on site.
- In the morning. On weekdays, pets that stayed overnight must be collected before 8am and taken home or back to your regular vet, who handles follow-up care.
Two more to know about
- The Referral Centre, Hamilton. The Referral Centre says animals hospitalised there have vet supervision and onsite nursing 24 hours a day, seven days a week. It works with referrals from your vet, so it is not a walk-in emergency clinic; ask your vet if your pet needs ongoing critical care.
- Auckland's 24/7 hospitals. The nearest hospitals we found that say they run a 24/7 emergency service are in Auckland, listed in our Auckland emergency vet guide. For most Hamilton emergencies, a local vet is the faster option.
After-hours hospital or your regular vet?
In a city with a 24/7 hospital, you can go there at any hour. In Hamilton, the time of day decides it. During the day from Monday to Thursday, call your regular vet first, because they are open and know your pet. CareVets, for example, says that in a medical emergency during its normal hours you should come directly to your nearest clinic and ring ahead if you can. Ask your own clinic now how it handles emergencies, rather than in a crisis.
From 6pm Monday to Thursday, from 9am on Friday through the weekend, and on public holidays, ring the Waikato After Hours Veterinary Hospital. It runs a triage system, like a human emergency department: a nurse assesses each animal on arrival and the most urgent are seen first, so a stable pet may wait.
If you do not have a regular vet yet, sign up with one this week. A clinic that already has your pet's records can act faster.
When is it an emergency? Go now
The Waikato After Hours Veterinary Hospital gives rat poisoning, being hit by a car, seizures, bleeding and eating chocolate as examples of emergencies, and says that if you feel your pet needs emergency treatment, do not hesitate to call or come in. Also treat these as urgent:
- Difficulty breathing, collapse or sudden weakness
- Retching that brings nothing up, with a swollen belly
- Repeated vomiting, or vomiting with blood
- A male cat straining in the litter tray with little or no urine
- Anything poisonous eaten, including bait, algae or human medicine
- Difficulty giving birth
Which Waikato emergencies should I know about?
These are the urgent risks that official New Zealand sources warn about.
Toxic algae in lakes and the river: go now
LAWA (Land, Air, Water Aotearoa), run with New Zealand's regional councils, says dogs are at the greatest risk from toxic algae because they play and scavenge in water. If you suspect your dog has eaten toxic algae, treat it as an emergency and contact your vet immediately. Signs include lethargy, muscle tremors, rapid breathing, twitching, paralysis and convulsions. Keep your dog on a lead and out of water that looks like pea soup, and if it has been in the water, wash it with fresh water and stop it licking its fur. Waikato Regional Council posts current lake and river alerts on LAWA's Waikato warnings page; check it before a swim.
1080 bait in forest parks: go now
If you take your dog walking or hunting in bush areas, the Department of Conservation says dogs are highly susceptible to 1080 poisoning, usually from eating poisoned carcasses rather than bait, and that the outcome is usually fatal. Look for DOC's warning signs at track entrances and keep dogs out until they come down, usually four to eight months after a drop. If you think your dog has eaten bait or a carcass, call the vet, say you suspect 1080, and go immediately: DOC says there is no antidote, but dogs can sometimes be saved with early action. DOC's page also lists first-aid steps; read it before the trip.
Heat
The Waikato gets warm summer days. The SPCA lists the signs of heat stress as excessive panting, drooling or hyperventilating, and seeking shade. Never leave a dog in a parked car. If you see a dog in a hot car, the SPCA says to act immediately and call the SPCA on 0800 SPCA NZ or the Police. A dog that collapses or cannot settle after heat needs a vet now.
Poisons at home
Rat bait and chocolate are on the hospital's own list of emergencies. For advice on whether something swallowed is dangerous, the National Poisons Centre says it is not expert in animal poisonings and points pet owners to their vet or the NZ Animal Poisons Helpline on 0800 869 738, which charges for its service. If your pet is already unwell, call the vet first.
What should I do on the way to the emergency vet?
- Call first. Say what happened, your pet's species, size and age, and when you will arrive. The hospital can prepare and tell you about the wait.
- Keep yourself safe. A frightened or hurt animal can bite, even a gentle one. Move slowly and keep your face away from its mouth.
- Carry your pet safely. Put cats and small dogs in a carrier. Lift a larger dog on a towel, blanket or board held by two people, keeping the back straight if it cannot walk.
- Bring what you can grab in a minute. Any packet, plant or bait your pet ate, your pet's medicines, and identification if you might apply for finance.
- Do not give human medicines. Many are toxic to dogs and cats. Give nothing by mouth unless the vet tells you to.
- Have a second person drive if you can, so someone can watch your pet.

The Waikato After Hours Veterinary Hospital does not publish a consultation fee, so we do not quote one. Emergency care is expensive, and the consultation is only the start. Here is what the hospital says about paying, from its FAQ:
- Estimate and deposit. It gives an estimate range, because an exact quote is not always possible, and asks for a deposit of the low end of that range before treatment or surgery starts. The balance is due at discharge.
- Insurance. Insured owners still pay, because the hospital cannot contact insurers after hours. It provides the medical notes and invoice for your claim.
- Finance. It lists Q Card and Afterpay. If you apply at the clinic, bring identification and allow an extra half hour. It also says it accepts cash.
Q Card and Afterpay are credit products, each with its own fees, limits and approval checks. Read the terms before you sign. The best time to sort out how you would pay a large bill is before an emergency, with pet insurance (check its after-hours cover and waiting periods) or a savings buffer.
What about injured wildlife?
For a sick or injured native animal, call the Department of Conservation hotline, 0800 DOC HOT (0800 362 468). For non-native wildlife, DOC says to contact your local SPCA or a wildlife rehabilitator.
Set this up before you need it
- Register with a regular vet and save its number, plus 07 839 5656 for the after-hours hospital.
- Learn the gap. Monday to Thursday 8am to 6pm, and Friday until 9am, are your vet's job; evenings, the weekend from Friday 9am and public holidays are the after-hours hospital's.
- Keep a carrier and an old towel where you can reach them quickly.
- Know your pet's weight, medicines and microchip number, or keep a photo of the adoption paperwork on your phone.
- Decide how you would pay a deposit at short notice.
If you are adopting, ask the rescue for the dog's or cat's vet history and which treatments are due next. Rescue pets usually arrive desexed, microchipped and vaccinated, so the emergency plan is the next job.
