Extensive plans were made and approved by the Government for her conversion to gas turbine propulsion, for long ranged resource protection patrols of New Zealand's newly declared 200-mile EEZ, reputed to be the fourth largest in the world.
It was perceived they would be cheaper to refit and the deal was sealed when the RNZN was made the exclusive offer of HMS Bacchante, a similar vintage broad beam Leander to HMNZS Canterbury, as well as HMS Dido which was being offered on the world market to any buyer, acceptable to the UK, partly to pay off the $50 million (23m pounds UK) cost of Dido's 1975-78 modernisation which had required an enormous amount of very expensive hull repair work on the then 15-year-old frigate.
The cost of its refit was as high as that of the greater scale conversion of later Leanders to Exocet missile and Lynx helicopter operation and appeared to match that of the final new Type 21 frigates.
