Winston Peters is backing the Retirement Commissioner's proposal to tighten up on immigrants getting superannuation.
But he disagrees with her call to raise the pension age from 65 to 67.
Commissioner Diane Maxwell has proposed raising the residency requirement from 10 to 25 years before a person can get superannuation. The Government said it would review her recommendations.
The New Zealand First leader said his party had long called for the residency requirement to be increased.
Maxwell's raft of suggestions including increasing the residency requirement, raising the age of eligibility and resuming contributions to the New Zealand Superannuation Fund were released as part of her three-yearly review of retirement policy.
