The NZIC online programming contest series, run by the New Zealand Olympiad in Informatics, is continuing in 2021! There will be 3 rounds. In each round, students choose a time during the week of that round to solve a selection of programming problems. The difficulty ranges from entry-level implementation problems to more challenging algorithmic problems. You can find examples on our training website.

The contest is open to all students currently enrolled in a secondary school (or intermediate) in New Zealand (students from year 7-13). There will be a scoreboard for individuals, and one for schools. You can view the results and solutions for previous rounds here. Past problems are avaliable for practice on our training website.


Registration for NZIC 2021 is now open!

What is Informatics?

In the context of this competition, informatics involves problem-solving with computer programs. Problems of a mathematical nature are posed, and students will write a computer program to solve the problem. The competition tests the efficiency and correctness of the algorithms the students come up with. The use of a programming language is not the goal itself, but rather a method by which a solution is expressed. A big part of informatics is breaking down and understanding the problem itself.


There will be 3 rounds in the NZIC 2021. Contest weeks are:

  • Monday Feb 22 to Sunday Feb 28
  • Monday Apr 12 to Sunday Apr 18
  • Monday Jul 5 to Sunday Jul 11


Log in to our training site and start the competition at any point between the above dates. Once a student has begun the competition they typically have 3 hours to view the problems and submit solutions. During their 3 hours, students are not permitted to access any websites (other than or collaborate with any others. This is an individual contest. You are, however, permitted to consult the documentation for your chosen programming language during the contest - remembering syntax can be hard. For details, please view the offical rules.

If you’re at a school with multiple students wanting to participate you might want to arrange to all sit it at the same time, either after school or during class time (with a teacher’s support).

What now?

We recommend some practice first. Sign up at and have a go at some past NZIC rounds. The contest is held on this training site and problems will be of a similar format. You will also save reading time during the contest.
