Westpac has been accused of hypocrisy over punishing Kiwi farmers for their emissions while investing in fossil fuels.

Westpac is among the major banks that introduced emissions reduction targets for farmers - including reducing the emissions intensity of the dairy farms it finances in Australia and New Zealand.

However, these targets translate into Westpac Australia allowing Australian dairy farmers to continue producing more CO2-equivalent emissions per tonne of milk than New Zealand dairy farmers.

Chief executive Catherine McGrath says Kiwi dairy farmers start at a better level than their Australian counterparts.
