NZ Lotto is a free lottery information app developed by Wing Chan for Android users. It offers the latest draw information and past results for the New Zealand lottery. The app also provides in-depth analysis of lottery numbers, including hot and cold numbers, odd and even numbers, and number zones. Additionally, NZ Lotto offers charts to track frequencies and distributions of lottery numbers for the last 10, 20, 40, and 100 draws. Users can also generate random numbers with the app's built-in tool.

It's important to note that NZ Lotto is not an official app from any official lottery organizations or entities. The app does not allow users to purchase tickets and all information provided is for reference only. Users should always check their tickets at an official outlet before discarding.
