Just five months after taking over a cafe at Whiritoa, Katherine Frame and Gary Davidson have found themselves at the hub of the coastal community despite dwindling supplies and no electronic payment facilities.

The town has been lashed by nearly 300mm of rain in less than 36 hours, and the Daisy Chain Cafe owners have had many locals come in to share their stories about what's going on and who has been flooded.

"Although we've got no cellphone coverage or Eftpos we've managed to get the word out that we've got hot scones and food here," Mrs Frame said.

"I've been doing a lot of home baking as the delivery trucks haven't been able to get through."

Since early Tuesday morning the couple - both trained special needs teachers - have heard tales about flooded homes and listened to locals' concerns about further rain expected tonight.

The couple bought the cafe five months ago after moving from Auckland three years ago.
