Location essentially doesn't matter for polar orbits, other than for safety purposes. (Technically, most polar orbits are not quite 90 degrees, and thus get some benefit from the Earth's rotation, which is greater when closer to the equator. But for high-inclination orbits, the cosine losses mean that this is a pretty marginal effect.) Electron will be mostly used for low-orbit missions, as geosynchronous sats will generally be too large for it. GEO missions are equatorial, and will benefit from being launched close to the equator. Small sats in low orbits will generally be observation (which often go into a sun-synchronous orbit, which is nearly polar) or radio relay constellations (which will go into highly-inclined orbits like 60 degrees). So for the likely payloads, their launch site is just fine. And, in reality, the benefit of equatorial launch isn't generally big enough to overcome logistical problems. Only Arianespace has bothered to establish a remote equatorial launch site... because Europe has essentially no appropriate launch site and they had to put one elsewhere anyway.
