Navigational Safety Warning - Mapua

Wednesday 6 June 2012, 3:36PM
By Tasman District Council


Users of the Mapua Wharf and Channel area are advised of the following:

1. A floating pontoon has been installed adjacent to the Mapua wharf. The access ramp between these two structures, and signage to advise of specific hazards, has not yet been installed. Both structures remain closed to vessels until further notice, except with prior authorisation from the Harbourmaster.

2. Several aids to navigation are being installed in the approaches to Mapua. Until these are formally notified via Notices to Mariners they should not be relied upon for navigation. Function and positioning has not yet been confirmed.

3. A pile for one of the above new aids to navigation has been reported absent following severe sea conditions overnight. This is a 12m long pole, approximately 300mm in diameter, fitted with a panel of reflective tape and a 4.5m steel ladder. Any one finding this should secure it ( if safe to do so) and report it’s position as soon as possible to the Harbourmaster, phone 03 543 8400 or email

4. Until this pile has been located, mariners should assume that it presents a hazard to navigation, and may be afloat in Tasman Bay or laying submerged in or near the Mapua channel/Rabbit Island area. Navigate with extreme caution in this area until further notice.
