WW1 had significant social, cultural, economic, and environmental impacts on New Zealand. The war positively impacted the economy by strengthening agricultural exports to Britain in exchange for New Zealand's assistance. However, it also increased costs of living. Socially, there was initial excitement around New Zealand's involvement, though the war psychologically damaged returning soldiers and put young inexperienced boys in danger. Culturally, the war brought Māori and Pākehā communities together by fighting alongside one another and having women work jointly. The military installations constructed altered the landscape environmentally. Overall, the war was a double-edged sword for New Zealand with both benefits and drawbacks across many domains.
