Check out the following link; https://www.charities.govt.nz/im-a-registered-charity/running-your-charity/how-to-fund-your-charity/

In addition to what’s been said above charities can also be funded via 2 broad strategies, these are as follows;

1) Grants strategy – normally provided by another charitable organisation or high net worth/high net worth family – there is a grant database or grant register that shows all the grants that are available – see the link above. You’ll need to go through this register and see if you can find grants that fit your cause.

2) Grateful patient strategy – this is where you appeal to families or organisations that your cause is close to their heart. Normally this is families that have suffered as a direct result and are more inclined to donate to your cause. This is a longer-term strategy of fundraising, however, once you have built this database it is very powerful.

Hope this helps.
