New data has revealed the average cost of a funeral in New Zealand has surged to $14,000 - and one charitable organisation hopes to help Kiwis bring these costs down.

Advocacy group Death Without Debt believes a DIY funeral can be done for little more than $1,000 - if people know how.

Convenor Fergus Wheeler says families could manage the process with no loss of dignity and for far less.

"Things like - moving a body around, not to embalm a body. You can register the death yourself, you don't need a funeral director to do that."
