The story
Founded by Jamie Selkirk, Peter Jackson and Richard Taylor in 1993.1
2000s
The studio has developed several proprietary software packages to achieve groundbreaking visual effects. The scale of the battles required for The Lord of the Rings film trilogy led to the creation of MASSIVE, a program which can animate huge numbers of agents—independent characters acting according to pre-set rules.
To recreate 1933 New York for King Kong, the company created CityBot, an application which could "build" the city on a shot by shot basis. Kong's fur also required the development of new simulation and modeling software. A set of tools that combined procedural and interactive techniques added wind to the five million individual strands of fur and modeled interaction with other surfaces. New shaders were written that accounted for the scattering of light from within each hair that added to the volumetric quality of the fur. Large chunks of fur were ripped out and filled in with scars, blood, and the mud of Skull Island. Each frame of fur took two gigabytes of data.
For James Cameron's Avatar, Weta Digital modified MASSIVE to give life to the flora and fauna on Pandora, for which the company did most of the visual effects with Joe Letteri, under a team led by executive and producer Eileen Moran. The film is regarded as a landmark for visual effects. By 2017, Weta Digital had started visual effects development for the sequels.
2010s
In 2010, a texture painting application developed by the studio for Avatar called Mari has been bought by The Foundry Visionmongers. For The Adventures of Tintin and Rise of the Planet of the Apes, the studio developed a new grooming system called Barbershop where users can interactively manipulate digital hair. This tool received a Sci-tech award in 2015. The Adventures of Tintin was Weta Digital's first fully animated feature film.
For Rise of the Planet of the Apes (2011), Weta developed a motion capture technique that could be utilized while shooting on location. The technology was improved for the sequel Dawn of the Planet of the Apes (2014), and was further refined for War for the Planet of the Apes (2017).
2020s
On June 19, 2020, Weta Digital announced that it would be producing original animation content under the name Weta Animated. The company also announced a new chief executive, Prem Akkaraju. In September 2020, Weta was able to secure a multi-year deal with Amazon Web Services to use the Amazon cloud to forward its VFX and computer animation production.
In December 2020, Weta Digital CEO Akkaraju announced additional board members including Tom Staggs, Jeff Huber and Ken Kamins. They join current board members Peter Jackson, Fran Walsh, Sean Parker and Joe Letteri.
On June 17, 2021, Weta Digital announced they have partnered with Autodesk to productize Weta's proprietary tools based in Autodesk Maya for a cloud service called WetaM. It will first be released in Q4 as a private beta. On August 23, 2021, Weta Digital announced a collaboration with SideFX for a cloud service combining the studio's proprietary tools within SideFX's Houdini called WetaH.

On November 9, 2021, Jackson sold the company's VFX tools development division to video games software company Unity Technologies for US$1.625 billion. Unity's acquired tech assets of Weta would be called Weta Digital, while the visual effects company remained separate and was renamed Wētā FX. The acquisition was completed in December 2021. In April 2022, Wētā FX opened a new studio in Vancouver, Canada. It is the company's first dedicated VFX and animation studio outside New Zealand. In July 2022, Wētā FX opened a second studio outside New Zealand, a temporary facility in Melbourne, Australia.
For Avatar: The Way of Water in 2022, Wētā worked on 3,240 visual effects shots, 2,225 of which involved water. The studio developed new motion capture technology for the film's underwater sequences. The digital water in the film was created by artists using Wētā's latest Loki simulation software. Wētā also refined their Facial Action Coding System (FACS) from Alita: Battle Angel for its use in Avatar: The Way of Water. The company eventually ended up rendering close to 3.3 billion thread hours. Letteri won his fifth Academy Award for his work on the film. The studio also won their seventh Academy Award for Best Visual Effects.
On November 25, 2023, Unity and Wētā FX mutually agreed to terminate Unity’s service agreement with Wētā FX effective December 10, 2023; this comes after Unity laying off the entire Wētā Digital staff in a "company reset". Unity will continue to own the software from the Wētā Digital acquisition (with Wētā FX being able to continue using them), but the Wētā Digital name and related intellectual property will be transferred back to Wētā FX with no current plans to use the old Wētā Digital name. Wētā FX will be extending offers to as many of the Digital team as possible "as it looks to expand its research, development and support functions".
For Kingdom of the Planet of the Apes in 2024, Wētā used new techniques to create even more realistic apes, including the use of dual-camera facial rigs to capture performance with greater fidelity than the previous films in the franchise, as well as evolving software for tasks such as muscle simulation, facial animation and grooming. Wētā also utilized machine learning, as well as new third-generation performance-capture suits for filming. In total, more than 1,000 artists were involved and the film contains over 1,500 visual effects shots. Water simulation technology and techniques from Avatar: The Way of Water were carried over. The team also created high-resolution digital environments as well as hair and cape simulations tuned to interact correctly with the simulated wind and airflow for James Gunn's Superman in 2025. For Avatar: Fire and Ash, Wētā collaborated with Industrial Light & Magic for the performance capture process. Wētā delivered 3,132 shots — 94% of the 195-minute film — requiring 1,248,087,308 render hours, or roughly 142,000 years of computation on a single processor. At peak production, the studio generated approximately 200–250TB of data per day, ultimately occupying 140PB of disk space. For their work on the film, the studio won their eighth Academy Award for Best Visual Effects. Wētā FX was responsible for 94% of the film's visual effects shots and over 1,200 artists worked on Avatar: Fire and Ash.
In April 2025, Wētā FX expanded its presence in Melbourne. After originally operating from a temporary facility during the production of Better Man, the company established a permanent Australian headquarters. On June 11, 2025, Lee Berger was appointed as business development senior producer. In early August 2025, Wētā proposed laying off 100 jobs in its support departments based in Wellington. In November 2025, Wētā and Amazon Web Services announced an agreement to explore the development of AI tools specifically designed for visual effects artists. On December 9, 2025, Wētā signed a memorandum of understanding with AMD to explore the development of next-generation rendering and AI tools aiming to optimize VFX workflows.
