Surprised this hasn't been posted before but it appears didymo is now present in Arthurs Pass in the creek by Devil Punchbowl falls and likley the Bealey & Mingha rivers so its possible that down and upstream rivers will be affected in time which will include Edwards and Hawdon.
Because of the nature of river crossings in Arthurs pass and people not cleaning there gear on each crossing its likely this will spread to most rivers in the park over time.
Link below, but it is reported on the main Arthurs Pass site that its likely in Bealey and Mingha rivers.

Is there any rivers that have Didymo and Blue Duck present in them?
An urgent rebuild of the system BirdingNZ runs on has resulted in loss of posts made over the past week.
