Bosworth Field: where are you?

This came up from a spontaneous email discussion with another Auckland historian over early cricket in Auckland, of all things. I did as one these days would do, and consulted Papers Past. These came up.

Southern Cross, 25 January 1845

New Zealander, 6 December 1845

I have no idea at this stage exactly where Bosworth Field was in early Auckland. Beyond 1845, the name vanishes, a mystery in smoke.
