Kahu Road – The gates to Riccarton House were originally in Straven Road. In May 1926 the driveway was shortened and the gates moved to Kahu Road. First appears in street directories in 1928. Mrs Edith Deans is one of the three residents listed.
A small amount of information from the library website. Some websites have this street in Riccarton and others have it in Fendalton. Papers Past had sections for sale in 1926 and in 1940s. There were also ads in 1926 that said Kahu Rd was a new street. Many of the ads for Kahu Rd also mention Rata St and both being off Straven Rd. There is a Rata St off Shand Crescent so it is likely to be a different Rata St.
There was an obituary for Mrs Catherine Edith Deans widow of John Deans on 06/09/1937.
There were several meanings for Kahu online and it is possible that harrier hawk is one meaning. Another meaning was cloak
A mixture of new and old houses. Some of the new houses had been rebuilt similar to the demolished houses. There is an entrance to Riccarton House here but I don’t know if the original gates are still there. The houses are lovely but I am not sure that I would like to live here as parking would be dreadful.
Different websites had this street in different suburbs.
