Hannah says they felt spurred into action at the sight of people suffering. They know the act of sending a card can't solve everyone's problems, but it's certainly a touching gesture that can mean a lot during dark times.
"This is such a heavy and sad time for New Zealand," Hannah says.
"My hope is that people see this as an avenue to do something when they may be struggling to know what to do or not be in a financial position to give much."
There is no card cut-off date, so when you're ready, send your cards to:
Sending Love, PO Box 90701, Victoria Street West, Auckland 1142.
Hannah and her helpers will then distribute them to mosques in Christchurch, the Christchurch hospital, plus the wider Muslim community and those impacted, wherever possible.
"All cards will be reviewed before distribution, so please leave your envelopes open," reminds Hannah.
"Cards should be filled with love, and genuine and authentic messages from the heart, and this is open to kids, adults, schools, organisations, community groups, etc."
