New Zealand Maths Olympiad Committee online

The January problems are an easy set of problems, aimed mainly at students who are only just entering the arena of “Olympiad style” problem solving. However, they will still be good practice for those who intend to do the September problems. As the months progress, problems in this series will gradually get more difficult.

Unusually, solutions to these problem sets will actually be posted, typically with a two month delay. However, as usual, solutions can be obtained at any time by sending an email providing evidence of some serious attempt to do the problems.
