Senior Cabinet minister Gerry Brownlee will represent the New Zealand Government at the funeral of former British prime minister Margaret Thatcher.
The 87-year-old died peacefully in her sleep after suffering a stroke in London on Monday.
Baroness Thatcher from the Conservative Party was prime minister from 1979 to 1990 and the first woman to hold the role.
Lady Thatcher had been in poor health for several years and her funeral will be held at St Paul's Cathedral in London with full military honours on Wednesday.
She will not have a state funeral, but will be accorded the same status as Princess Diana and the Queen Mother.
Buckingham Palace says the Queen and the Duke of Edinburgh will attend.
