"The report by Deloitte found Westpac NZ had improved its liquidity control environment and did not identify any material control gaps or issues.
"However, we agree that further refinements can be made and we'll be building that into our continuous improvement activity.
"Our team has put significant effort into enhancing our risk culture and we were pleased to see that acknowledged in the report. We will continue to maintain a strong focus in these areas.
"Westpac NZ's current liquidity and funding positions are sound, and the bank is well capitalised."
RBNZ deputy governor Christian Hawkesby said it was encouraged to see that Westpac NZ had taken the necessary steps to improve its liquidity risk management and risk culture by increasing its resourcing and improving its governance processes.
"We expect that the momentum built to date will allow Westpac NZ to continue the overall transition from a reactive, to a proactive risk culture."
"We appreciate Westpac NZ's cooperation with the review process and maintain our assessment that Westpac NZ's financial position is sound."
