Its BB+/B long and short term ratings were affirmed.In fact, S&P went on to say the positive rating outlook reflects its expectations that the ratings could be raised to 'BBB-/A-3' if the company continues to successfully manage its low-risk and sound credit profile through to 2011, a period when the nonbank deposit-taking sector in New Zealand is expected to come under pressure.
