Kawaiicon (previously Kiwicon) is a New Zealand computer security conference held in Wellington from 2007. It brings together a variety of people interested in information security. Representatives of government agencies and corporations attend, along with hackers.

The conference format allows for talks, informal discussions, socialising, key signing and competitions. Talks are of various lengths on a wide range of subjects, usually including a wide range of techniques for modern exploits and operational security, security philosophy, New Zealand hacker history, related New Zealand law, and a few talks on more esoteric topics.

Kiwicon was founded by Adam Boileau when the annual Australian computer security conference Ruxcon was cancelled for 2007. After ten annual conferences Kiwicon took a break in 2017; in 2019 Boileau stepped down and the conference was relaunched in a "less elaborate" form as Kawaiicon. After two conferences, Kawaiicon took a break before announcing a return for 6-8 November 2025.

The inaugural Kiwicon was held during the weekend of 17–18 November 2007 at Victoria University of Wellington. Approximately 200 people from the New Zealand security community (and elsewhere) attended the two-day event. Talk topics included: the psychology of user security errors, information warfare, hiding files in RAM, cracking with PlayStation, and attacks on: kiosks, telecommunications company Ethernet, non-IP networks, and a serious Windows hole.

Kiwicon 2k8 was held on 27 and 28 September, with an attendance of over 250 people. A broader range of attendees arrived, with presale tickets selling out before the doors opened. Attendees were greeted with an array of video phone captures proving the insecurity of video conferencing systems. Topics included: mass surveillance, using honeypots to detect malicious servers, physical security, using search engine optimization to make websites disappear from search results, Bluetooth surveillance, Internet probe counterattacking, speed hacking, and attacks on: wired and mobile phone systems, biometrics, Citrix XenApp, and Windows Vista via heap exploitation.

Kiwicon 2k9 was held during the weekend of 28-29 November 2009 at Victoria University of Wellington for the third year running. The event sold out with an attendance of over 350 people. Talk topics included: professional vulnerability research, identifying online identities using Bayesian inference, social engineering, radio sniffing, defending against denial-of-service attacks, Linux rootkits, an introduction to the New Zealand Internet Task Force, and attacks on: physical access control systems, GPS, smart cards, shared hosting platforms, ActiveSync, iOS App Store, pagers, wireless routers, and scientific software.

Kiwicon IV was once again held on the weekend of 27-28 November 2010 at Victoria University of Wellington, and sold out even earlier than in 2009. The title was a play on the term Four Horsemen of the Infocalypse. Some talk topics included: a survey of unpatched devices connected to the internet, fast data erasure, urban exploration, web scraping, wardriving with Arduino, New Zealand's proposed Search and Surveillance Act, and attacks on: RFID tags, Internet exchange points, Amazon Kindle, Microsoft Office and Java serialization.

For its fifth year, Kiwicon took place on 5 and 6 November 2011, at a much larger venue, the Wellington Opera House. The slogans and the date of the event referenced Guy Fawkes and the Gunpowder Plot. Among the talk topics were: an example attack on a film studio, policing hacking from organised crime gangs, operational security, "cyberwarfare", New Zealand's new file-sharing law, automated memory corruption exploitation, Mac OS rootkitting, and attacks on: NFC transactions, iPhones, Android, and garage door openers.
