Young people are being urged to have their say on how to protect New Zealand from climate change.

The New Zealand Youth Delegation is calling on young kiwis to make a submission to the government's climate change consultation which closes on Wednesday.

Spokeswoman Natalie Jones says it's vital they take the chance to make their voices heard as they will be the most affected by the problem and have done the least to contribute to it.

Simple online submissions can be made on the 'fix our future' website.
