Frazer v Walker [1967] 1 AC 569[1] is a landmark New Zealand court case that went to the Privy Council on appeal.

On 29 November 1962, Mr Walker was duly registered as the new legal owner of the farm on the property title.

The Frazers appealed his claim to ownership to the farm to the Privy Council, where the earlier decisions were upheld.

The Privy Council ruled that while the legal interest in the land may have been originally obtained by fraud, because Mr Walker was unaware of any fraud at the time of purchase (a bona fide purchaser for value without notice, under section 183 of the Land Transfer Act), meant that he had indefeasible title to the farm.

In a wider sense, this case is important due to its affirmation of the immediate nature of indefeasible title under section 62 of the New Zealand Land Transfer Act 1952, following Boyd v Mayor of Wellington.
