The February 2026 Notices to Mariners bring a notable collection of updates that skippers should work through before their next passage. Several affect well-known cruising areas. Others concern the administration of ports and protected zones that are changing right now, not at some future point.
New marine protected areas are now active across the Hauraki Gulf, and that is the development most likely to catch skippers off guard. These are not proposed measures or consultation outcomes still working their way through a process. They are in force. The protections differ depending on the zone in question. Some restrict particular fishing methods. Others place limits on anchoring and any activity that disturbs the seabed. Places that skippers have treated as straightforward stopping points for years may now fall inside areas carrying specific conditions.
The practical complication is that chart updates will come later. In the meantime, the Notices to Mariners themselves and Department of Conservation guidance are the sources that carry regulatory weight. Electronic charts remain useful, but they are not a substitute for knowing where restrictions apply. That responsibility sits with the person on the helm.
Tauranga Harbour is another area demanding fresh attention. Dredging is actively underway between A Beacon and Town Reach Beacon, and a temporary lit starboard lateral buoy has been placed to reflect the changed conditions. Further adjustments to navigation aids are possible as the work continues. Spoil grounds D and G have both been temporarily extended, with revised boundaries described by position. Charts NZ 541 and the associated harbour plans are among those affected.
Skippers who know Tauranga well should resist the temptation to trust a familiar route without checking current information. Channels shift, marks get repositioned, and depths change as dredging progresses. For anyone planning to anchor or transit close to the dredged area, a call to the harbourmaster is the most reliable way to get an accurate picture before entering.
On the west coast, Whanganui Port calls for particular care. Dredging is taking place along wharves 1 and 2, with two spoil grounds currently in use and a temporary pile installed near one of them. The more significant concern for visiting vessels is the North Head Bar leading lights, which are unlit until further notice. For a bar crossing, that matters. The leading lights provide the alignment that becomes critical when conditions are anything less than ideal. Without them, skippers need to place greater weight on timing, daylight, thorough local knowledge, and genuinely cautious judgement. Habit or past experience is not enough here.
Skippers operating along the lower east coast should be aware that three Otago area charts have been flagged for new editions. No immediate action is required, but the notice signals that recent survey work or a build-up of corrections has made new releases necessary. Checking current chart editions and being ready to update when those releases appear is sensible preparation.
The general notices also include a recommendation that vessels using ECDIS systems run the official ENC data presentation and performance check produced by the International Hydrographic Organization. Concerns have been raised at an international level about certain systems failing to render important chart features correctly. The test dataset gives operators a straightforward way to confirm that their system is displaying information as it should. The recommendation is directed mainly at commercial operators, but the underlying point applies across the board. Electronics support navigation. They do not carry the responsibility for it.
