Many banks have put in place emergency packages, including help such as suspending loan repayments and extending overdrafts and credit limits.
Christchurch branches of some of the main banks remain closed due to damage and many of the ATMs are not working.
Fundraising efforts continue
A Ruatoria-based iwi radio station is running a 24-hour radiothon to raise funds for Christchurch.
Radio Ngati Porou hopes some of the money from the event on Thursday can pay for flights to get people home to family in Gisborne and on the East Coast.
Family plans to help others in need with gifted money
A couple whose North Brighton family were gifted more than $1000 by a fundraiser says she's going to use some of the money to help others.
The money was gifted to Sally and Nelson Warner by a Tauranga woman who started a concept called adopt-a-family, which raises money especially for one affected family.
Mr and Mrs Warner say they may be unemployed because of the quake, so some of the money will help pay bills, and the rest will go to others on their street who need food and water.
The organiser says she's fielding calls from around the world from people who want to adopt a family themselves.
