Wet Summer Lifts Duck Numbers—What Wellington Hunters Need for Opening Weekend

A wet start to the year has boosted mallard survival and delayed harvests, setting up a stronger duck hunting season in the lower North Island. Here’s what to expect.

A run of wet weather across the lower North Island has set the tone for the upcoming duck hunting season, with more mallards expected than last year.

Lower North Island hunters are heading into this weekend’s opening (May 2/3) with a rare bit of optimism: Wellington Fish & Game manager Phil Teal says several factors have lined up after a summer marked by frequent weather events, from mild disruption to heavier rain.. By the region’s standards, the season has been “pretty rubbish” in day-to-day terms—but it has created conditions that are unusually favourable for young ducks.

Why the wet summer could mean more mallards

Teal’s main point is straightforward: the wet conditions arrived at a crucial time for young ducks, helping them find food and shelter more easily.. When water is available and feeding areas stay productive, survival tends to improve.. He also links the overall outlook to a delayed crop harvest across the region, which matters because mallards are opportunistic feeders.

With maize and grain available from recently harvested paddocks, ducks can move in briefly to feed rather than having to search farther afield. If the harvest is pushed later than usual, ducks may also remain locally for longer, extending the period when hunters see them on the same landscapes.

The season outlook and practical hunting advice

Fish & Game monitors mallard numbers each year using transect surveys from small aircraft.. Teal says this year’s monitoring work points to an around 16 per cent increase in mallard numbers compared with the previous season.. That doesn’t mean every area will look the same on opening morning, but it does suggest a wider base of birds across parts of the lower North Island.

There is, however, a clear trade-off.. While strong bird numbers can lift expectations, torrential rain and higher water levels can also change how ducks behave.. Teal expects more standing water to be present than in a typical start, meaning ducks may have more options for feeding and roosting.. For hunters, that can translate into less certainty about where birds will be showing up.

In practice, the advice is to be ready to adapt: have back-up spots in mind if the “chosen possie” doesn’t deliver as planned. It’s the kind of season where a single plan may not be enough, because weather can keep shifting the distribution of waterfowl from hour to hour.

Opening weekend culture—and why patience matters

Over 5,000 duck hunters are expected to be in the Wellington Fish & Game region across opening weekend, spanning the area between Cook Strait and Waiouru.. Duck hunting is more than just a pastime for many people.. Teal describes it as a tradition that brings friends and families together, often for the only shared get-together of the year—mixing a practical hunt with social time afterwards.

For rural landowners, the season also creates a recurring moment of cooperation, as many allow hunters onto their properties.. And while those community ties are part of the appeal, the regulator’s focus remains on safety and compliance.. Teal encourages hunters to hunt throughout the season, not just on the opening rush.

That longer view matters because opening weekend weather can be bright and calm in some years—conditions that tend to make hunting harder since ducks are able to fly higher.. Teal says better waterfowl hunting weather often comes later, so hunters should make use of their game bird licence and get out regularly after opening.

Licence checks, bag limits, and safety reminders

Any duck hunt depends on doing the basics correctly. Teal notes that a valid game bird licence is required, available via Fish & Game’s website and also at outdoor supplies stores. Rangers will be active across the region, with support from Police officers, checking for compliance.

Before heading out, hunters are advised to confirm they understand the regulations and season bag limits, and to follow firearms safety rules.. The wet summer may be boosting mallard numbers, but the season still runs on preparation—especially when rain and standing water could reshape where birds decide to feed..
