Politicians across the board have brushed off growing calls to lift the retirement age. Retirement Commissioner Diana Crossan this afternoon lashed out over the Government's response to her three-yearly review of retirement income policy. The Government rejected Crossan's call for the age of eligibility for New Zealand Super to be gradually increased to 67 by two months a year up to 2033. "The Government has said the status quo should remain, but something needs to change to keep New Zealand Super affordable in the long term," Crossan said. "Politicians appear to have their heads in the sand about the issue of the raising the age of eligibility." Prime Minister John Key has promised to resign rather than allow the retirement age to increase. He reiterated the promise this afternoon. "I've given a very strong commitment to the public of New Zealand (not to lift the age)," Key said.
