As a Kiwi, I would just check out that "
Manahan Heads. Actually, I've never heard of of it and think it could probably be
Manakau Heads, which is one of the entrances to Auckland Harbour in the North Island. Manakau itself was the third biggest city in New Zealand, although that may have changed with recent boundary changes in Auckland. (I'm not an Aucklander so not up with the play up there)!

Hope this is helpful, just thinking, kau can very easily look like han, if the reader is not familiar with Maori placenames. Certainly not criticising, just a friendly observation. Have another look and see if it could be
ManakauJeanne
