A midsummer festival named “Carnival of the Lake” was held on the Hokowhitu Lagoon at Centennial Drive, Palmerston North, January 17th – 20th 1964. A variety of activities ensured the public were well entertained during the four day festival. Here, three Navy divers, from a party of five, tested equipment as part of their display at Centennial Lake [Hokowhitu Lagoon]. They were all members of the Royal New Zealand Navy Diving School based at HMNZS Philomel. The Carnival of the Lake was organised by the Palmerston North Public Relations Organisation and held over Anniversary Weekend in 1963 and 1964.
