The Labour Party says it has taken a breach of privilege complaint against the Prime Minister over comments he made to Parliament about the scrapping of the KiwiSaver kickstart.
Labour alleges John Key misled the House in May when he said Inland Revenue advised him the removal of the $1000 kickstart contribution would not have an impact on enrolments.
Its finance spokesperson Grant Robertson said Budget documents released yesterday showed Inland Revenue said scrapping the kickstart would result in a lower numbers of KiwiSaver members.
Mr Robertson said it was important Labour made a complaint as misleading statements lowered the integrity of Parliament.
"It calls into question whether or not statements that are being made in Parliament are accurate."
However, the Budget document also said KiwiSaver is a costly and poorly targeted savings scheme and removing the kickstart would improve the scheme's value for money.
