It's estimated that 115.3 million animals are used every year in the name of science around the world.¹

In New Zealand, around 300,000 animals are used for research, testing and teaching every year. Thousands of these animals will be subject to cruel and archaic animal experiments and killed.

Animals used for science in NZ

The graph below shows the number of animals who have been used for science in NZ from 2000 - 2022.

Animals killed for science in NZ

Thousands of animals are killed during or after being used for science in NZ, this includes:

• Animals who died or were euthanised during or after manipulations.
• Animals who were killed for their tissues (this has only been monitored by the NZ Government since 2018).

The graph below shows the number of animals who have been used and killed for science in NZ from 2000 - 2022.

Additional animals killed for science in NZ

There are also additional animals who are killed - these are animals who have bred for science, never used, and are therefore killed as "excess" animals. This has only been monitored by the NZ Government since 2019.

The graph below shows the total number of animals who were killed because they were bred for science but were never used in NZ from 2019 - 2022.

We don't take these numbers lightly; each animal who has been killed matters, and we'll continue working hard to end animal experimentation once and for all — together, we are creating a world where no animal dies in the name of science
