Mr English said the increase was "the fairest way" to ensure EQC could meet its long-term costs and most homeowners' bills would rise by "a relatively small increase" of about $2.65 a week.
"It will put a bit more pressure, particularly on some homeowners who are full stretched on servicing their mortgages.
"But we think under the circumstances, in order to shore up the EQC's finances, it's an extra bit that households will be able to handle."
AA Insurance head of corporate affairs Suzanne Wolton said the levy increase was expected "but it does pose some significant challenges for home insurance customers for whom the affordability of home insurance is now becoming an issue".
AA Insurance customers' premiums for building insurance had risen about $250 because of higher reinsurance costs, "now they've got to find another $140".
Labour's finance spokesman David Cunliffe said his party supported the rise:
"The country can't afford not to have an EQC, it needs to be built back up and the fairest thing to do is to increase that levy".
