[8][9] Alien Weaponry are believed to be youngest recipients to have ever received New Zealand on Air funding with their song "Rū Ana Te Whenua" in October 2015.

[14] On 17 February 2019, the band (alongside Radio New-Zealand) released a ten part documentary series entitled: 'Alien Weaponry Shake Europe', that documented their European tour the year prior.

[4][17] In official video declaration Ethan Trembath said that the reason of leaving the band is: "health and my own happiness" also being away from home and pursuing a career in making music in studio.

Rick Sales is the long-standing manager of Slayer and also represents other notable metal artists such as Gojira, Mastodon and Ghost in his small exclusive portfolio.

In January 2018 the band went back into the studio with producer Hammerhead to continue work on their first full-length album which included some of their biggest hits, Kai Tangata and Holding My Breath.

The Māori lyrics refer to events that occurred in the Bay of Islands in the 1800s and what followed after a pocket watch was inadvertently dropped into the harbour.

The band says, "This incident is used in this song as a metaphor for the misunderstandings that continue to plague us today – between cultures, generations and individuals who torment each other through lack of understanding."

[citation needed] The band's second single "Raupatu" (released in February 2017) is about land confiscations by the New Zealand colonial government in the 1800s and the legislation of 1863 that allowed it to happen.

[30] Guitarist Lewis de Jong cites Stevie Ray Vaughan, Lamb of God, System of a Down, Meshuggah, and Polyphia as influences.
